PART A:
Make the authoring tool user interface accessible
Applicability Notes:
Scope: The success criteria in Part A apply to all aspects of the authoring tool user interface that are under the control of the developer. This includes functionalities that are independent of the content being edited, such as what is sometimes referred to as the authoring tool's "chrome" (e.g., menus, button bars, status bars, etc.) and also user preferences and documentation, etc. In addition, the developers' responsibility covers certain aspects of other functionalities that reflect the content being edited (e.g., ensuring that an image label present in the content is available programmatically). However, where an accessibility problem in the user interface is caused directly by an accessibility problem in the content it is reflecting (e.g., if an image in the content lacks a label), then this would not be considered a deficiency in the accessibility of the authoring tool user interface.
PRINCIPLE
A.1: Authoring tool user interfaces must follow applicable accessibility guidelines
Guideline A.1.1
[For the authoring tool user interface] Ensure that Web-based
functionality is accessible.
[Techniques]
[Return to Guideline]
Rationale: In
addition to generally improving the accessibility of the authoring
tool user interface, implementing Web-based functionality (e.g., editing views, documentation) using accessible Web content facilitates communication with assistive
technologies via user agents.
A.1.1.1 Web-Based Accessible (Level A): Web-based authoring tool user interfaces conform to WCAG Level A. (Level A)
- Technique A.1.1.1-1 [Sufficient]: Following
the requirements of WCAG Level A when developing any Web-based functionality.
- Technique A.1.1.1-2 [Advisory]: Testing Web-based authoring tool user interfaces using automated evaluation and repair tools.
- Example: Throughout development of an authoring tool, with the tool in various representative states, the editing interface (including test content being authored) is tested using accessibility evaluation software. Problems are corrected and the process iterates
A.1.1.2 Web-Based Accessible (Level AA): Web-based authoring tool user interfaces conform to WCAG Level AA. (Level AA)
- See Techniques for A.1.1.1 using WCAG Level AA.
A.1.1.3 Web-Based Accessible (Level AAA): Web-based authoring tool user interfaces conform to WCAG Level AAA. (Level AAA)
- See Techniques for A.1.1.1 using WCAG Level AAA.
Applicability Notes:
This guideline also applies to parts of authoring tools that are Web-based (e.g., help systems).
Guideline A.1.2
[For the authoring tool user interface] Ensure that non-Web-based functionality is accessible. [Techniques] [Return to Guideline]
Rationale: Following existing accessibility standards and/or platform conventions will facilitate access by all authors, including those using assistive technologies.
A.1.2.1 Non-Web-Based Accessible (Level A): Non-Web-based authoring tool user interfaces comply with, and cite in the conformance claim, the "Level A" requirements of standards and/or platform conventions that benefit accessibility. The "Level A" requirements are those that are functionally equivalent to WCAG Level A success criteria. (Level A)
- Technique A.1.2.1-1 [Sufficient]: Implementing the input, focus, selection and product installation sections of accessibility guidelines and best practice documents that are relevant to the platform. These may include:
- Eclipse: "Designing Accessible Plug-ins in Eclipse" [ECLIPSE-ACCESS]
- Gnome/KDE:
- Java:

A.1.2.2 Non-Web-Based Accessible (Level AA): Non-Web-based authoring tool user interfaces comply with, and cite in the conformance claim, the "Level AA" requirements of standards and/or platform conventions that benefit accessibility. The "Level AA" requirements are those that are functionally equivalent to WCAG Level AA success criteria. (Level AA)
- See Techniques for A.1.2.1 using WCAG Level AA.
A.1.2.3 Non-Web-Based Accessible (Level AAA): Non-Web-based authoring tool user interfaces comply with, and cite in the conformance claim, the "Level AAA" requirements of standards and/or platform conventions that benefit accessibility. The "Level AAA" requirements are those that are functionally equivalent to WCAG Level AAA success criteria. (Level AAA)
- See Techniques for A.1.2.1 using WCAG Level AAA.
Applicability Notes:
This guideline also applies to parts of authoring tools that are non-Web-based (e.g., client-side file uploaders).
PRINCIPLE
A.2: Editing views must be perceivable
Guideline A.2.1
[For the authoring tool user interface] Provide access to alternative equivalents in the content.
[Techniques]
[Return to Guideline]
Rationale: People
who have difficulty perceiving non-text objects are often able to
access text alternatives of the same information because there are a variety of ways to display text (e.g., magnification, enhancement, text-to-speech, Braille output)
A.2.1.1 Alternative equivalents in the content:
Editing
views that render non-text content (e.g., WYSIWYG) provide authors with access to any equivalent alternatives recognized by the authoring tool. (Level A)
Technique A.2.1.1-1 [Sufficient]: In editing views that render non-text objects, displaying in an editable fashion any text alternatives
(e.g., short text labels, long text descriptions) associated with the objects (e.g., within a properties dialog).
- Technique A.2.1.1-2 [Advisory]: Providing the equivalent alternatives via an accessiblity platform architecture.
- Technique A.2.1.1-3 [Advisory]: When appropriate for a Web technology (i.e., the technology is human-readable), providing an source content editing view that allows direct editing of all properties.
Technique A.2.1.1-4 [Advisory]: Providing an option to toggle between rendered non-text objects and the text alternatives for the objects.
- Example: An option to toggle fully rendered images with their text alternatives.
On the left is the image (of the "earth rise" as seen from the
moon) rendered as usual. On the right is a different rendering, this
one including an area for editing the alternate text and a link to edit the
long description. A small preview rendering of the image is included
to provide context. (Source: mockup by AUWG)

Technique A.2.1.1-5 [Sufficient]: In editing views that render multimedia, also displaying any associated synchronized alternatives (e.g., captions for video, captions for audio files, audio descriptions for videos).
Applicability Notes:
This guideline does not apply to plain text editors as they do not render non-text content.
Guideline A.2.2
[For the authoring tool user interface] Provide programatic access to all information in the editing view.
[Techniques]
[Return to Guideline]
Rationale: Authors need to have access to and control over both the functional significance of presentation and also, in the context of authoring, the presentation that will be experienced by the end user. This is especially important for user interface components that do not implement an accessibility platform architecture or leverage existing implementations (e.g. custom user interface components built via JavaScript and CSS). Some authors require display settings that differ from the presentation that they intend to define for the published content (e.g., using a high contrast setting during editing content that is not intended to be high contrast).
A.2.2.1 Purpose of Added Presentation: If the authoring tool modifies the presentation of the content being edited, then the functional purpose for the modification is made available via the platform (e.g., if misspelled text is underlined, the fact that it is misspelled is made available). (Level A)
- Technique A.2.2.1-1 [Sufficient]: Making available programmatically the semantics of any presentation that is added to the editing view by the authoring tool.
- Example: A change tracking feature displays inserted text in green and deleted text in red with a strike through. Instead of implementing this using simple CSS selectors, the XHTML elements
ins
and del
are used, since they have associated semantics.
A.2.2.2 Access to Text Presentation (Minimum): If an editing view (e.g., WYSIWYG) renders any of the following text presentation properties and those properties are editable by any editing view (e.g., instruction level), then the properties are made available via the platform (Level A):
- (a) font,
- (b) style (e.g., italic, bold),
- (c) color, and
- (d) size.
- Technique A.2.2.3-1 [Sufficient]: Making available via the platform, information on the size, font, foreground and background color, font weight, and position of any text that is under the control of the author.
Example: Using a WYSIWYG authoring tool, an author is able to mark a paragraph using a "footnote" style class, then query the text to check on the rendered size of the text to ensure that the styling information has been picked up properly.
A.2.2.3 Access to Text Presentation (Enhanced): Any text presentation properties (text size, positioning, etc.) that are rendered in an editing view (e.g., WYSIWYG) and are editable by any editing view are available via the platform. (Level AAA)
- See Techniques for A.2.2.2, but for all text presentation properties rendered and editable by the authoring tool.
Guideline A.2.3: Ensure the independence of the authors' display preferences.
Rationale: Some authors will require display settings that differ from the presentation that they intend to define for the published content (e.g., an author uses large fonts for themselves, while editing content that is not intended to have a large font in the final content).
A.2.3.1 Independence of Display: Editing
views that usually have their display characteristics set
by rendering the content being
edited (e.g., WYSIWYG) allows the authors' visual and audio display settings to override these characteristics without
affecting the content being edited (e.g.,
markup, style sheets, etc.).
(Level A)
- Technique A.2.3.1-1 [Sufficient]: Providing
the author with the ability to change the fonts, colors, sizing (zoom), etc.
within rendered editing views (or by changing the platform display settings), independently
of the ability to control the markup that is actually produced.
Example: A WYSIWYG authoring tool includes editing interface controls for setting the text and background colors as they will appear to the end user, but also includes a "View" area in its preference settings, where the author can choose to override the WYSIWYG rendering with their own text and background color settings.
- Technique A.2.3.1-2 [Advisory]: Allowing the author
to specify a preferred style sheet that is used in the editing view to override the actual "published" style of
the document.
PRINCIPLE
A.3: Editing views must be operable
Guideline A.3.1
[For the authoring tool user interface] Enhance keyboard access to authoring features. [Techniques] [Return to Guideline]
Rationale: Providing alternate keyboard accessibility provides access for people with limited mobility and people with
visual disabilities, who cannot rely on hand-eye coordination for
navigating the user interface.
A.3.1.1 Important Command Functions: If the authoring tool includes any of the following functions, authors can enable
key-plus-modifier-key (or single-key) access to them (where allowed by the operating environment) (Level A):
- (a) open help system,
- (b) open new content,
- (c) open existing content,
- (d) save content,
- (e) close content,
- (f) cut/copy/paste,
- (g) undo/redo, and
- (h) open find/replace function.
- Technique A.3.1.1-1 [Sufficient]: Providing key-plus-modifier-key (or single-key) access for all of the functions listed here.
- Example: On a Windows platform, an authoring tool uses the following keyboard commands: opening help system (e.g., F1); open new content (e.g., ctrl-N); open existing content (e.g., ctrl-O); save content (e.g., ctrl-S); close content (e.g., ctrl-W); cut/copy/paste (e.g., ctrl-X, ctrl-C, ctrl-V); undo/redo (e.g., ctrl-Z, ctrl-Y); open find/replace function (e.g., ctrl-F, ctrl-H).
- Technique A.3.1.1-2 [Advisory]: Following platform conventions when choosing keystrokes, such as:
- Technique A.3.1.1-3 [Advisory]: Expanding direct keyboard access beyond the functions listed in this success criterion to other frequently used functions of a tool (e.g., to perform text formatting, move quickly between windows, etc.)
A.3.1.2 Importing Content Keyboard Trap: The authoring tool prevents keyboard traps as follows (Level A):
- (a) in the UI: if keyboard focus can be moved to a component using the keyboard, then focus can be moved away from that component using standard sequential keyboard commands (e.g., TAB key) and
- (b) in the rendered editing views: provides a documented direct keyboard command that will always restore keyboard focus to a known location (e.g., the menus) and
- (c) in the rendered editing views: provides a documented direct keyboard command that will always move keyboard focus to a subsequent focusable element
Guideline A.3.2
[For the authoring tool user interface] Enable time-independent interaction.
[Techniques] [Return to Guideline]
Rationale: People
who have difficulty typing, operating the mouse, or processing information
can be prevented from using systems with short time limits.
A.3.2.1 Data Saved: If the authoring tool ends an authoring session due to a time limit (e.g., authenticated session expires), then authors have the global option to ensure that the content being edited is saved. For Web-based authoring tools, this applies to any content that has already been submitted to the server by the user agent. (Level A)
A.3.2.2 Timing Adjustable: The author is warned before time expires and given at least 20 seconds to extend the time limit with a simple action (e.g. "press the space bar").
(Level A)
- Technique A.3.2.2-1 [Sufficient]: Providing a preference setting to universally extend all authoring tool-controlled time limits.
- Technique A.3.2.2-2 [Sufficient]: Allowing the author to extend authoring-controlled time limits whenever they occur.
A.3.2.3 Moving Targets: If the user interface includes any moving targets for authors' actions (e.g.,a selectable component of an animation), then authors can stop that movement.
(Level A)
- Technique A.3.2.3-1 [Sufficient]: All components that can be targets for author actions can be stopped.
- Example: In a timeline-based animation editor, a draggable time indicator moves when the animation is being previewed. This movement can be stopped with the "Stop" button.
Applicability Notes:
Several of the success criteria in this guideline only apply when there are time limits put on the author.
Guideline A.3.3
[For the authoring tool user interface] Help authors avoid flashing that could cause seizures. [Techniques] [Return to Guideline]
Rationale: Flashing
can cause seizures in people with photosensitive epilepsy.
A.3.3.1 Static View: If an editing view renders content (e.g., WYSIWYG) then the author has the global option of a static view in which time-based content appears in a fixed state. (Level A)
Guideline A.3.4
[For the authoring tool user interface] Enhance navigation and editing via content structure. [Techniques] [Return to Guideline]
Rationale: People who have difficulty typing or operating the mouse benefit when authoring tools use the structure present in the content to simplify navigation and editing.
A.3.4.1 Edit by Structure: If an editing
view displays a structured
element set, then authors can, with a simple action, select
any element in
the set and perform editing functions (e.g., cut, copy, paste, presentation)
on that element, its contents, and its sub-elements.
(Level A)
- Technique A.3.4.1-1 [Sufficient]: Ensuring that when an element is selected, any content, including sub-elements, of the element are also selected. Then, ensuring that when a selected element with content, including sub-elements, is the subject of an operation (cut, copy, styling, delete) the element's content should also be subject to the same operation unless the operation targets the element only. Note that various editing functions will apply differently when performed on a selected element. These differences might be classified according to their scope, as follows:
(a) "element, content and sub-elements": These functions target the entire selection. Examples of these functions include cut, copy, and delete.
- Example: In an HTML editor , when a
<table>
element is selected and the "delete" operation is performed, the entire table is deleted including sub-elements ( <tr>
and <td>
) and any text content etc. within the table.
- (b) "element only": These functions only target the top level element of the selection, even if the effect cascades down to sub-element content when it is rendered. Examples of functions of this type include, "Emphasis" which should apply styling to the top level element (e.g.,
<p>
) while not making any source changes to sub-elements (e.g., strong) (even though the content of sub-elements may be rendered differently) and “strip element tags” that deletes the markup of the top level element without affecting its sub-element.
- Example: In an HTML editor, when a
<table>
element is selected and the "strip element tags" operation is performed, the operation targets the <table>
only, so this set of tags is removed, leaving sub-elements ( <tr>
and <td>
) and any text content etc.
- (c) "content and sub-elements only": These functions target the content, including sub-elements of the top level element of the selection without having any affect on the markup of that top level element. An example of this might be a “Replace Contents” function:
A.3.4.2 Navigate By Element Type: If an editing view displays a structured element set, authors can move the editing focus forward/backward to the next identical element. (Level AA)
A.3.4.3 Navigate By Headings: If an editing view displays a structured element set, authors can move the editing focus forward/backward to the heading, regardless of level. (Level AA)
A.3.4.4 Navigate Tree Structures: If an editing
view displays a structured
element set, authors can, with a simple action, move
the editing focus from any element to
other elements in the set with any of the following
relationships (if they exist) (Level AA):
- (a) Parent: the element immediately
above,
- (b) Child: the first element immediately
below,
- (c) Previous Sibling: the element immediately
preceding at the same level, and
- (d) Next Sibling: the element immediately
following at the same level.
- Technique A.3.4.4-1 [Sufficient]: Providing the ability to move focus from any element to the element that contains it (i.e., parent element), if any. Also providing the ability to move focus from any element to the first sub-element that it contains (i.e., first child element), if any. Also providing the ability to move focus from any element to the element immediately preceding it as a sub-element of the same parent element (i.e., previous sibling). Also providing the ability to move focus from any element to the element immediately following it as a sub-element of the same parent element (i.e., next sibling).
Example: An authoring tool in which a <tr>
element
has current focus and is therefore highlighted in the editing view. As
well, breadcrumbs in the status bar trace the path from the root element
to the current element, <html> <body> <table> <tr>
.
A pop-up menu from the selected element shows that keystrokes are available
to move the selection focus to the parent element, <table>
,
of the current element, to the child elements, in this case two <td>
elements
and to the next and previous element pointed to by the same parent element
(in this case to preceding and following <tr>
elements).
(Source: mockup by AUWG)

- Technique A.3.4.4-2 [Advisory]: Providing an "outline"
or "structure" view of the document that organizes the structured element set into a document tree or graph.
- Technique A.3.4.4-3 [Advisory]: If loops are possible within the structured element set, providing a mechanism for alerting the author when they have completed a loop.
- Technique A.3.4.4-4 [Advisory]: Ensuring that a smooth transition exists between navigation via the content structure to a particular element and commencing to edit that element.
Guideline
A.3.5 [For the authoring tool user interface] Provide
text search. [Techniques] [Return to Guideline]
Rationale: People
who have difficulty typing or operating the mouse benefit from the ability to navigate to arbitrary points within editing views.
A.3.5.1 Text Search: A function is provided that allows text search of the content, which meets the following conditions (Level AA):
- (a) Search All Editable: can search any textual information (including
text content, text
alternatives for non-text
objects, metadata, markup) that is editable using the authoring tool.
- (b) Bi-Directional: can search backwards and forwards. [UAAG 2.0]
- (c) Case Sensitive: can search in both case sensitive and case insensitive modes. [UAAG 2.0]
- (d) May Switch Views: permissible to require authors to switch editing views to perform search results (e.g., from WYSIWYG to instruction level to search for markup tags).
- Technique A.3.5.1-1 [Sufficient]: Supporting bi-directional, case sensitive searching for plain text sequences within the content (i.e., text between the open and close tags of an element, text in a content management database) and within text alternatives for non-text content (i.e., short text labels, long text descriptions, etc.) even when this textual information is actually encoded as part of the markup (e.g., as an attribute value).
- Example: Searching for a term yields occurrences within regular page content but also in the alt-text of images, long descriptive text, and metadata values.
- Example: Searching for the text string "able", with the source code option checked, yields results that include
<table>
elements.
- Technique A.3.5.1-2 [Advisory]: Providing structure-based searching that takes into account structural roles and relationships.
- Example: A search facility that makes effective use of structure. Here the author has chosen to find the "element" with the name "img", "with attribute" "height" "equal to" "100", where each value in quotation marks was editable. The replacement action is to "set attribute" "height" to "50". The following checkbox options are available "match case", "ignore white space" and "search text alternatives". The facility also includes the following buttons "Find Next", "Find all", "Replace", "Replace All", "Close" and "Help". (Source: mockup by AUWG)

- Technique A.3.5.1-3 [Advisory]: Providing more advanced search options, such as:
- text search options such as replacement, wildcard characters, whole word matching, search repetition, and highlighting of all occurrences.
- option to search the content only, the markup only, or both.
- use metadata (per WCAG 2.0 [WCAG20]) to assist searching of large collections, or of timed presentations.
- for tools that manage a database or multiple files, provide a search function that can search through the different pieces of content at once.
- allow the author to select an area by similarity to the search probe (e.g., closeness of color in an image editor, etc.)
Guideline A.3.6
[For the authoring tool user interface] Manage preference settings. [Techniques] [Return to Guideline]
Rationale: Providing
the ability to save and reload sets of keyboard and display preference
settings benefits people using multi-user tools as well as people who have needs that differ over time (e.g., due to fatigue).
A.3.6.1 Save Settings: Preference settings are stored for any of the following that the authoring tool controls
(i.e., not controlled by the platform) (Level AA):
- Technique A.3.6.1-1 [Sufficient]: Storing configuration options (not controlled by the platform) for (a) keyboard operability, (b) the visual display, (c) for the auditory display.
- Example: In a Web-based authoring tool, the author must log in. Once they do, they are presented with display/control preferences profiles that they have previously customized. The author can change their profile at any time.
A.3.6.2 Multiple Sets: Choosing between multiple sets of preferences (e.g., personal profiles,
personal settings) are supported for any of the following that the authoring tool controls (i.e., not controlled by the platform) (Level AAA):
- Technique A.3.6.2-1 [Sufficient]: Providing the option of multiple configuration sets of options. Each set contains the configuration settings (not controlled by the platform) for (a) keyboard operability, (b) the visual display, (c) for the auditory display.
A.3.6.3 Options Wizard: Authors are provided with an accessibility option-setting "wizard" to configure options related to Part A.
(Level AAA)
- Technique A.3.6.3-1 [Sufficient]: Providing a wizard that walks the user through the configuration options, providing explanations and previews of how the configuration options will change the display.
- Example: The wizard follows an interview format, asking the author about general preference areas (e.g., seeing the screen, using the keyboard) and only becoming more detailed if the author affirms an area.
Guideline A.3.7
[For the authoring tool user interface] Ensure that previews are
as accessible as existing user
agents. [Techniques] [Return to Guideline]
Rationale: Preview features
are provided in many authoring tools because the workflow of authors often includes periodically checking how content will appear
to end users in
a user
agent. Authors with disabilities need to be able to follow
the same workflow.
Note: Previews are treated differently than editing views because authors, including those with disabilities, will not be well-served if preview features diverge too much from the actual functionality of available user agents. Therefore, preview features are exempted from necessarily having to meet all of the other requirements in Part A of this guidelines document, if they meet this guideline.
A.3.7.1 Return Mechanism: If a preview is provided, then it is possible to return from the preview using a simple action which is documented in the help system. (Level A)
A.3.7.2 Preview: If a preview is provided, then it meets at least one of the following (Level A):
- (a) Existing User Agent: the preview makes
use of an existing user
agent that is specified in the conformance
profile (e.g., opening the
content in a third-party browser, browser component, video player, etc.)
- (b) Part A.1: the preview meets
all of the Level A guidelines in Principle A.1 of these guidelines, or
- (c) UAAG: the preview conforms
to the User Agent Accessibility Guidelines [UAAG].
- Technique A.3.7.2-1 [Sufficient]: Allowing the author to locate a user agent on the platform with which to perform the preview).
- Technique A.3.7.2-2 [Sufficient]: For Web-based authoring tools that are already running in a user agent, use that same user agent to perform be the preview.
- Technique A.3.7.2-3 [Advisory]: Allowing
the author to maintain a list of user agents to be used for previewing.
- Technique A.3.7.2-4 [Advisory]: Helping the author to find a user agent to perform the preview, by auto-scanning the system for known user agents.
- Technique A.3.7.2-5 [Advisory]: Bundling user agent installer files or providing a list of download sites for appropriate user agents.
- Technique A.3.7.2-6 [Sufficient]: Ensuring that the entire preview (content view and the rest of the user interface) meets all of the requirements of Part A that might be applicable to a browser.
- Technique A.3.7.2-7 [Sufficient]: Providing conformance tests to show that the preview feature meets UAAG 1.0.
PRINCIPLE
A.4: Editing views must be understandable
Guideline A.4.1 [For the
authoring tool user interface] Help users avoid and correct mistakes.
[Techniques]
[Return to Guideline]
Rationale: People who have difficulty making fine movements may be prone to making
unintended actions.
A.4.1.1 Undo Content Changes: Authoring actions are either reversible by an "undo" function or include a warning
to authors that the action is irreversible. (Level A)
A.4.1.2 Undo Setting Changes: Actions
that modify authoring tool settings are either reversible or include a warning
to the author that the setting modification is irreversible.
(Level A)
- Technique A.4.1.2-1 [Sufficient]: All setting changes are reversible using the preferences.
A.4.1.35 Redo: Authors can immediately reverse the most recent content "undo(s)" (i.e., a "redo" function).
(Level AA)
- Technique A.4.1.3-1 [Sufficient]: Including undo actions in the queue of the five most recent actions (see Techniques for A.4.1.1).
A.4.1.47 Multiple Undos: Authors can reverse
at least 5 consecutive reversible authoring actions.
(Level AAA)
- Technique A.4.1.4-1 [Sufficient]: Maintaining a queue of the five most recent actions (from most to least recent) and providing a function that can reverse the actions one-by-one starting with the most recent.
Applicability Notes:
- Web-based authoring tools may rely on the "undo" function of the user agent listed in the conformance profile to perform the undo function for some editing actions that do not involve server communication (e.g., typing in a text area).
- It is acceptable to collect text entry actions (e.g., typed words, a series of backspaces) into a single reversible authoring action.
- It is acceptable for certain committing actions (e.g., "save", "publish") to reset the undo history.
Guideline A.4.2
[For the authoring tool user interface] Document the user interface
including all accessibility features.
[Techniques]
[Return to Guideline]
Rationale: While
intuitive user interface design is valuable to many authors, some
people may still not be able to understand or be able to operate
the authoring tool user interface without proper documentation.
A.4.2.1 Document Accessibility Features: All features that are specifically required
to meet Part
A of these guidelines (e.g.
keyboard shortcuts, text search, etc.) are documented.
(Level A)
- Technique A.4.2.2-1 [Sufficient]: Documenting all aspects of the user interface covered by Part A of these guidelines (including keyboard accessibility, display configurability, etc.).
- Technique A.4.2.2-2 [Advisory]: Providing a documentation index to accessibility features.
- Technique A.4.2.2-3 [Advisory]: Providing additional forms of help, including context sensitive help.
A.4.2.2 Accessibility Feature Tutorials: Tutorials are provided for some of the features that are specifically required to meet Part A of these guidelines. (Level AAA)
Applicability Notes:
The accessibility of the documentation is covered by Guideline A.1.1 and A.1.2.
PART
B: Support the production of accessible content
Applicability Notes:
- Authors Availability: Any success criteria in Part B that refer to authors only apply during authoring sessions when authors are available.
- Responsibility After Authoring Sessions: Authoring tools are not responsible for accessibility problems that result from carrying out instructions made by the author during authoring sessions (e.g., the content of a third-party feed specified by the author), but they are responsible if the changes are automatically generated (e.g., the developer makes site wide changes to a CMS).
- Existing Technologies: The success criteria in Part B only apply to support for accessible authoring practices that are relevant to technologies that the authoring tool already has the ability to create or edit. For example, a markup authoring tool that adds images by simply linking to their URIs would be required to support the production of alternative text for images in the markup, but it would not be required to add image editing functionality to ensure sufficient contrast in case any images are of text.
- Authoring Systems: As per the definition of authoring tool, several software tools can be used in conjunction to meet the requirements of Part B. (e.g. a authoring tool could make use of a 3rd party software accessibility checking and repair program.
PRINCIPLE
B.1: Production of accessible content must be enabled
Guideline B.1.1 Support Web content technologies that enable the creation of content that is accessible.
[Techniques]
[Return to Guideline]
Rationale: Choosing technologies which support the possibility of accessible authoring is the first step in ensuring that the content produced is accessible.
B.1.1.1 Tool Choice of Technologies (Level A): Any Web content technologies that are automatically selected by the authoring tool can conform to WCAG Level A.
(Level A)
- Technique B.1.1.1-1 [Sufficient]: A Web content technology could be considered able to conform to WCAG Level A if multiple content developers have publicly claimed WCAG Level A conformance for content developed using the technology.
Example: A content management tool is implemented using HTML templates, JavaScript and CSS for both the user interface and author generated content. One factor in the developer choosing this combination of technologies is that Web resources already exist that are implemented using these technologies and that have publicly claimed WCAG Level A conformance.
- Technique B.1.1.1-2 [Sufficient]: A Web content technology could be considered able to conform to WCAG Level A if a WCAG Techniques document exists for the technology, regardless of whether the author of the Techniques document is the W3C-WAI WCAG Working Group or a third party (e.g., the developer of a non-W3C document format).
- Technique B.1.1.1-3 [Sufficient]: Supporting W3C Recommendations, which have been publicly reviewed for accessibility. References include:
B.1.1.2 Author Choice of Technologies (Level A): If the authoring tool provides authors with Web content technology options, technology options that can conform to WCAG Level A are listed with at least as much prominence as any other options and the tool guides the author towards the most accessible technology for the task.
(Level A)
- Technique B.1.1.2-1 [Sufficient]: When prompting authors to choose between technologies, begin the list with technology options that can conform to WCAG Level A (see Techniques B.1.1.1-1, B.1.1.1-2, B.1.1.1-3 for methods to determine the accessibility of the options).
- Example: An authoring tool only claims ATAG 2.0 conformance for HTML documents, but allows production of CSS style sheets, and MathML. When the author requests a new document, HTML is the first technology listed.
- Technique B.1.1.2-2 [Advisory]: Displaying a warning when the author chooses to create Web content with a technology that cannot conform to WCAG Level A or with a technology that theoretically could conform to WCAG Level A, but for which the authoring tool does not provide accessibility support.
- Example: A sample warning might read "Accessibility support is not available for documents in this format".
B.1.1.3 Tool Choice of Technologies (Level AA): Any Web content technologies that is automatically selected by the authoring tool can conform to WCAG Level AA. (Level AA)
- See Techniques for B.1.1.1 using level WCAG Level AA.
B.1.1.4 Author Choice of Technologies (Level AA): If the authoring tool provides authors with Web content technology options, technology options that can conform to WCAG Level AA are listed with at least as much prominence as any other options and the tool guides the author towards the most accessible technology for the task. (Level AA)
- See Techniques for B.1.1.2 using level WCAG Level AA.
B.1.1.5 Tool Choice of Technologies (Level AAA): Any Web content technologies that is automatically selected by the authoring tool can conform to WCAG Level AAA. (Level AAA)
- See Techniques for B.1.1.1 using level WCAG Level AAA.
B.1.1.6 Author Choice of Technologies (Level AAA): If the authoring tool provides authors with Web content technology options, technology options that can conform to WCAG Level AAA are listed with at least as much prominence as any other options and the tool guides the author towards the most accessible technology for the task. (Level AAA)
- See Techniques for B.1.1.2 using level WCAG Level AAA.
Guideline B.1.2
Ensure that the authoring tool preserves accessibility
information.
[Techniques]
[Return to Guideline]
Rationale: Accessibility
information is critical to maintaining comparable levels of accessibility
across transformations and conversions.
B.1.2.1 Accessibility Information Preservation (Minimum): If the authoring tool performs transformations or conversions on existing Web content,
then for any accessibility
information that is required for that content to conform to WCAG Level A at least one of the following is true (Level A):
- (a) Preserve in Output: the accessibility
information is preserved and available for end
users in the resulting content;
- (b) Preserve Input and Notify: a copy of the accessibility
information is retained (e.g., as a "comment", by saving a backup
copy) and the authors are notified of the location and of the fact that it will not be available to end users; or
- (c) Author Queried: the authors are queried for an action for each piece of accessibility information that will not be preserved and is notified that this may result in accessibility problems.
B.1.2.1 Target Preserves Accessibility Information : If the target technology of the transformation or conversion can preserve *recognized* accessibility information that is required for that content to conform to WCAG Level A, then the accessibility information is preserved and available for end users in the resulting content. (Level A)
B.1.2.x Target Cannot Preserve Accessibility Information: If the target technology of the transformation or conversion cannot preserve *recognized* accessibility information that is required for that content to conform to WCAG Level A, then the authoring tool (Level A):
- provides the author with the option to retain the information in another way if possible (e.g., as a "comment", by saving a backup copy) and
- notifies the author that this will result in accessibility problems in the target.
- Technique B.1.2.1-1 [Sufficient for (a)]: Preserve accessibility
information in similar data structures.
- Example: If converting between HTML and SVG the contents of
alt
attributes can be stored in desc
attributes.
- Technique B.1.2.1-2 [Sufficient for (a)]: Where necessary, preserve accessibility
information in a dissimilar, but accessible way.
- Example: If transforming a SMIL presentation with a closed-caption text track into a video-only format, provide the option of an open-captioned video.
- Technique B.1.2.1-3 [Sufficient for (b)]: Automatically archiving a backup copy of the original content if accessibility
information will be lost and notifying the author of both the location and the fact that the new location will not be available to end users needing the information.
- Technique B.1.2.1-4 [Advisory]: When importing images with associated descriptions into a markup document,
make the descriptions available through appropriate markup.
- Technique B.1.2.1-5 [Advisory]: Avoid transforming text into images. Use style sheets for presentation
control, or use an XML application that keeps the text as text.
If this is not possible, ensure that the text is available as equivalent
text for the image.
- Technique B.1.2-1.6 [Advisory]: Notifying the author before changing the technology (including the DTD) of the content being authored.
- Technique B.1.2.1-7 [Advisory]: Allow authors to edit transformation or conversion templates to specify the way presentation conventions should be converted into structural markup.
- Technique B.1.2.1-8 [Advisory]: Ensure that changes to graphical layouts do not reduce readability when the document is rendered serially. For example, confirm the linearized reading order with the author.
- Technique B.1.2.1-9 [Advisory]: When transforming a table to a list or list of lists, ensure that table
headings are transformed into headings and that summary or caption information
is retained as rendered content.
- Technique B.1.2.1-10 [Advisory]: When converting linked elements (i.e., footnotes, endnotes, call-outs,
annotations, references, etc.) provide them as inline content or maintain
two-way linking.
- Technique B.1.2.1-11 [Advisory]: When converting from an unstructured word-processor format to markup,
ensure that headings and list items are transformed into appropriate structural
markup (appropriate level of heading or type of list, etc.).
- Technique B.1.2.1-12 [Advisory]: When developing automatic text translation functions, strive to make the resulting text as clear and simple
as possible.
B.1.2.2 Accessibility Information Preservation (Enhanced): If the authoring tool performs transformations or conversions during an authoring session,
then any accessibility
information in the pre-transformation/conversion content that is required for content to conform to WCAG Level AA or AAA is preserved and available for end
users in the resulting content.
(Level AA)
B.1.2.3 Notification Prior to Deletion: If the authoring tool automatically deletes any author-generated content for any reason, then at least one of the following is true
(Level AA):
- (a) Preserve Accessibility Information: the authoring tool only automatically deletes content that it can detect is not accessibility
information;
- (b) Notification Option: authors have the option to receive notification before deletion; or
- (c) No Deletion Option: authors have the option to turn off the automatic deletion.
- Technique B.1.2.2-1 [Sufficient]: Detecting and avoiding the deletion of any author-generated content.
- Technique B.1.2.2-2 [Sufficient for (a)]: Detecting and avoiding the deletion of author-generated content that is accessibility
information.
- Technique B.1.2.2-3 [Sufficient for (b)]: Providing the author the option to confirm or override removal of content either on a change-by-change basis or as a batch process.
- Technique B.1.2.2-4 [Sufficient for (c)]: When an automatic process is to be performed that cannot be completed without removing content (even including unrecognized markup), providing the author with the option of canceling the operation.
Applicability Notes:
If an authoring tool performs transformations or conversions after an authoring session ends (e.g., a batch maintenance process) only option (a) is allowed for both B.1.2.1 and B.1.2.3.
Guideline B.1.3
Ensure that automatically generated content is accessible.
[Techniques]
[Return to Guideline]
Rationale: Authoring
tools that automatically generate content that is not accessible impose additional repair tasks on authors.
See Also: If accessibility
information is required from authors during
the automatic generation process, see Guideline
B.2.1. If templates or other pre-authored content are involved, see Guideline B.2.5.
B.1.3.1 Automatic Accessible (Level A): If the authoring tool automatically generates content, then that content meets WCAG Level A prior to publishing.
- Technique B.1.3.1-1 [Sufficient]: Ensuring that any action that the authoring tool takes without complete author knowledge that causes content to be added or modified has the result of not introducing new WCAG Level A contraventions.
<- Technique B.1.3.1-2 [Advisory]: Using prompting to elicit information from the author when necessary (see Guideline B.2.1).
B.1.3.2 Automatic Accessible (Level AA): If the authoring tool automatically generates content, then that content meets WCAG Level AA prior to publishing. (Level AA)
- See Techniques for B.1.3.1 using WCAG Level AA.
B.1.3.3 Automatic Accessible (Level AAA): If the authoring tool automatically generates content, then that content meets WCAG Level AAA prior to publishing. (Level AAA)
- See Techniques for B.1.3.1 using WCAG Level AAA.
Applicability Notes:
- This guideline applies to the automated behavior specified by the authoring tool developer under the assumption that authors will respond properly to any prompts.
- The guideline does not apply when actions of the authors prevent generation of accessible content (e.g., by setting less strict preferences, ignoring prompts for accessibility information, providing faulty information, writing their own automated scripts, etc.).
PRINCIPLE B.2:
Authors must be supported in the production of
accessible content
Applicability Notes:
-
Principle B.2 applies to authoring tool processes that interact with human authors, and the authoring choices that author is making or the authoring choices under the control of the authoring tool. Authoring choices include choice of style sheets, templates, scripts, etc
Guideline B.2.1 Guide authors to
create accessible content.
[Techniques]
[Return to Guideline]
Rationale: By guiding authors from the outset towards the creation and maintenance of accessible content, accessibility problems are mitigated and less repair and retrofit effort is required.
Implementation Notes: Prompting in the ATAG 2.0 context is not to be interpreted as necessarily implying intrusive prompts, such as pop-up dialog boxes. Instead, ATAG 2.0 uses prompt in a wider sense, to mean any tool initiated process of eliciting author input that is triggered by author actions (e.g., adding or editing content that requires accessibility information from the author in order to prevent the introduction of accessibility problems). The reason for this is that it is crucial that that accessibility information be correct and complete. This is more likely to occur if the author has been convinced to provide the information voluntarily. Therefore, overly restrictive mechanisms are not recommended for meeting this guideline. The author experience of prompting will be very similar to that of checking (see Guideline B.2.2) for some implementations. For example, in a tool that checks continuously for accessibility problems, the markings used to highlight discovered problems can be considered to be a form of prompting.
B.2.1.1 Guide Accessible (Level A): If authors are prompted for any information as content is being added or updated (e.g., by an image modification dialog), then the tool also prominently prompts for any accessibility
information required for that content to meet WCAG Level A.
(Level A)
- Technique B.2.1.2-1 [Sufficient]: Ensuring that all instruction text would, if followed exactly by the author, leads to content being created or modified so as to meet WCAG Level A.
- Technique B.2.1.2-2 [Sufficient]: Consistently labeling help documents or other documentation such that, if followed exactly by the author, it would lead to content being created or modified to not meet WCAG Level A.
B.2.1.3 Guide Accessible (Level AA): If authors are prompted for any information as content is being added or updated, then the tool also prominently prompts for accessibility information required for that content to meet WCAG Level AA.
(Level AA)
- See Techniques for B.2.1.1 using WCAG Level AA.
- See Techniques for B.2.1.2 using WCAG Level AA.
B.2.1.5 Guide Accessible (Level AAA): If authors are prompted for any information as content is being added or updated, then the tool also prominently prompts for accessibility information required for that content to meet WCAG Level AAA.
(Level AAA)
- See Techniques for B.2.1.1 using WCAG Level AAA.
- See Techniques for B.2.1.2 using WCAG Level AAA.
Guideline B.2.2 Assist authors in checking for accessibility problems.
[Techniques]
[Return to Guideline]
Rationale: Checking as an integrated function of the authoring tool helps make authors aware of accessibility problems during the authoring process, so they can be immediately addressed.
Implementation Notes: Despite prompting assistance from the tool (see Guideline B.2.1), accessibility problems may still be introduced. For example, the author may cause accessibility problems while coding by hand or by opening content with existing accessibility problems for editing. In these cases, the prompting mechanisms that operate when markup is added or edited (i.e., insertion dialogs and property windows) must be backed up by a more general checking system that can detect and alert the author to problems anywhere within the content (e.g., attribute, element, programmatic object, etc.). It is preferable that checking mechanisms be well integrated with repair mechanisms (see Guideline B.2.3), so that when the checking system detects a problem and informs the author, the tool immediately offers assistance to the author.
B.2.2.1 Check Accessibility (Level A): At least one individual check is associated with each WCAG Level A Success Criterion that the tool has the functionality to modify (e.g., a tool that inserts images should check for alt text; a tool that can edit captions should check for them).
(Level A)
- Technique B.2.2.1-1 [Sufficient]: Providing accessibility checking for the various success criteria in WCAG, identified as Level A. In some cases several checks may be required to appropriately test whether a WCAG success criterion has been met.
- Technique B.2.2.1-2 [Advisory]: Providing a listing of the checks performed in the conformance claim.
B.2.2.2 Availability: Checking is available prior
to publishing in a manner appropriate to the workflow of the authoring tool.
(Level A)
- Technique B.2.2.2-1 [Sufficient]: Providing accessibility checking as an action (e.g., as a menu item, etc.) at all times.
- Technique B.2.2.2-2 [Sufficient]: Prompting the author to perform an accessibility check if the author chooses to close or publish the content
B.2.2.32 Help Authors Locate: For any checks that require author judgment to determine whether a potential accessibility problem is correctly identified (i.e., manual checking and semi-automated checking), the relevant content is identified (e.g., displaying the surrounding text, "Is a sign lanuage interpretation provided?") (Level A)
- Technique B.2.2.3-1 [Sufficient]: Identifying the entire span of elements covered by a potential accessibility problem.
Example: A instruction-level authoring tool displays errors in a separate pane by the line number of the first element in the span.
Example: A instruction-level authoring tool displays errors in-line by underlining all of the markup for the affected span of elements.
Example: A WYSIWYG authoring tool displays errors in-line with the rendered content in the WYSIWYG editing view as blue outlining around or under the affected span of elements.
- Technique B.2.2.3-2 [Advisory]: Displaying manual checks in a way that balances the need for the author to make specific changes to some kinds of content (e.g., non-text objects, acronyms, table cells, etc.) while not overwhelming the author with numerous manual checks for other kinds of content that can be checked more generally (e.g., background color contrast, reading level, etc.). Excessively general checks (e.g., "does the page meet
all of the requirements?") should be avoided.
B.2.2.4 Help Authors Decide: For any checks that require author judgment to determine whether
a potential accessibility
problem is correctly identified (i.e., manual checking and semi-automated checking), instructions are provided
to help authors to
decide.
(Level A)
- Technique B.2.2.4-1 [Sufficient]: Ensuring that the wording of prompts answers the following questions: "What part of the content should be examined?" and "What is present or absent in the event that the problem exists?".
- Technique B.2.2.1-3 [Advisory]: Saving author judgments for manual checks and only prompting for new judgments after substantial changes is a more user-friendly approach.
- Technique B.2.2.4-2 [Advisory]: Providing preview modes to authors view their content in ways it may be viewed by others, but that they may not have considered:
- an alternative content view (with images and other multimedia replaced by any alternative content)
- a monochrome view (to test contrast)
- a collapsible structure-only view (to test keyboard navigation)
- a text to speech view (to test the availability of text alternatives)
- no scripts view
- no frames view
- no style sheet view
Example: A WYSIWYG authoring interface includes a list of rendering options as sub-menu options of a View menu. The options include "All" (i.e., render as in a generic browser), "text-only" (i.e., non-text items replaced by textual equivalents), "no styles", "no frames", and "grayscale" (used to check for sufficient contrast). In the background, the "earth rise" image in the WYSIWYG view can be seen in grayscale. (Source: mockup by AUWG)

B.2.2.5 Check Accessibility (Level AA): At least one individual check is associated with each WCAG Level AA Success Criterion that the tool has the functionality to modify.
(Level AA)
- See Techniques for B.2.2.1 using WCAG level AA.
B.2.2.6 View Status: If the authoring tool records accessibility problems
found during checking, then a list of any accessibility problems is available to authors prior to the end of the authoring session.
(Level AA)
- Technique B.2.2.6-1 [Sufficient]: Providing the option to view a single consolidated list of all of the accessibility problems that are detected by the checking function (see Guideline
B.2.2), organized by problem type and number of instances.
- Technique B.2.2.6-2 [Advisory]: Providing direct links to additional help and repair assistance from the list of accessibility problems.
B.2.2.7 Save Status for Repair: If repair assistance is not provided during checking , authors have the option to save the list to facilitate interoperability between checking and repair.
(Level AA)
- Technique B.2.2.7-1 [Sufficient]: Providing the option of storing accessibility
status information in a format that can be processed by a variety of tools (e.g., using Evaluation and Repair Language [EARL]).
B.2.2.8 Metadata for Discovery: If the authoring tool records accessibility status, then authors have the option to associate this status with the content as metadata to facilitate resource discovery by end users.
(Level AA)
- Technique B.2.2.8-1 [Sufficient]: Providing the option of storing accessibility
status information using the IMS AccessForAll Meta-data mechanism [ACCESSFORALL].
B.2.2.9 Check Accessibility (Level AAA): At least one individual check is associated with each WCAG Level AAA Success Criterion that the tool has the functionality to modify.
(Level AAA)
- See Techniques for B.2.2.1 using WCAG level AAA.
Applicability Notes:
- While automated
checking or more advanced implementations of semi-automated
checking may improve the authoring experience, manual checking is the minimum requirement to meet the success criteria for this guideline.
- This guideline does not apply if the authoring tool controls the authoring process to such an extent that it is not possible for authors to introduce accessibility problems.
- This guideline does not apply to content that is not available at publishing (e.g., the actual content of third-party "feeds").
Guideline B.2.3
Assist authors in repairing accessibility problems.
[Techniques]
[Return to Guideline]
Rationale: Repair as an integral part of the authoring process greatly enhances the utility of checking and increases the likelihood that accessibility
problems will be properly addressed.
Implementation Notes: Once a problem has been detected by the author or the tool (see Guideline B.2.2), the tool may assist the author to correct the problem. As with accessibility checking, the extent to which accessibility correction
can be automated depends on the nature of the problems. Some repairs
are easily automated, whereas others that require human judgment may be semi-automated
at best.
B.2.3.1 Repair Accessibility (Level A): For each WCAG Level A accessibility
problem that is identifiable during checking (required
in Guideline B.2.2), repair assistance is provided.
(Level A)
- Technique B.2.3.1-1 [Sufficient]: For each potential accessibility problem identified by the checking function (required in Guideline B.2.2), providing repair instructions that an author (with sufficient skill and knowledge to use the rest of the tool) could follow to correct the problem. At the developer's discretion, semi-automated repairs (that prompts the author for required information) or automated repairs (that are able to complete the repair without prompting the author) may be substituted.
- Technique B.2.3.1-2 [Advisory]: Providing as much automated repair as possible. Where necessary provide semi-automated repairing (see Appendix C: Levels of Repair Automation). Where neither of these options is possible, provide manual repairing.
- Technique B.2.3.1-3 [Advisory]: When appropriate, reusing affected elements' property editing mechanisms. This has the advantage that the author is already somewhat familiar with the interface. However, this practice does not necessarily focus the author's attention on the dialog control(s) that are relevant to the required correction.
- Technique B.2.3.1-4 [Advisory]: Implementing a special-purpose correcting interface, analogous to a spelling or grammar checker, that includes only the input field(s) for the information currently required. Additional information and tips that the author may require in order to properly provide the requested information can be added.
- Example: A special-purpose correction interface supports the author's repair task by providing (1) a short description of the problem (here: "Missing Alternate Text Label for an Image"), (2) a preview (here: the "earthrise" image that is missing a label), (3) tips for performing the repair (here: "Alternate text should be 10 words or less and should include any text in the image."; "Image buttons should have alternate text that describes the button function."; and "Image bullets should have "bullet" as alternate text."), and (4) an offered semi-automated repair in an editable drop-down box (here: "An earth rise as seen from the moon"). (Source: mockup by AUWG)

Technique B.2.3.1-5 [Advisory]: Presenting accessibility problems and repair options in a sequential manner analogous to a typical spelling or grammar checking "wizard". Because of the wider range of problems an accessibility checker needs to handle (i.e., missing text, missing structural information, improper use of color, etc.), the interface template will likely need to be especially flexible.
- Example: A sequential accessibility checker. The special-purpose correction interface from the previous example is supplemented by a progress indicator ("5 of 25") and navigation buttons to move backwards ("back") and forwards ("skip") through the list of repair tasks. Buttons to "repair", get "help" and "cancel" are also provided. (Source: mockup by AUWG)

Technique B.2.3.1-6 [Advisory]: Where an authoring tool is able to detect site-wide errors, allowing the author to make site-wide corrections. This should not be used for equivalent alternatives when the function is not known with certainty (see Guideline B.2.4).
- Technique B.2.3.1-7 [Advisory]: Providing a mechanism for authors to navigate sequentially among uncorrected accessibility errors. This allows the author to quickly scan accessibility problems in context.
- Technique B.2.3.1-8 [Advisory]: Consulting the Techniques for Accessibility Evaluation and Repair Tools [AERT] Public Working Draft document for evaluation and repair algorithms.
B.2.3.2 Repair Accessibility (AA): For each WCAG Level AA accessibility
problem that is identifiable during checking, repair assistance is provided.
(Level AA)
- See Techniques for B.2.3.1 using WCAG Level AA.
B.2.3.3 Repair Accessibility (AAA): For each WCAG Level AAA accessibility
problem that is identifiable during checking, repair assistance is provided.
(Level AAA)
- See Techniques for B.2.3.1 using WCAG Level AAA.
Applicability Notes:
- While automated
repairing or more advanced implementations of semi-automated
repairing may improve the authoring experience, only manual repairing is the minimum requirement to meet the success criteria for this guideline.
- This guideline does not apply if the authoring
tool controls the authoring process to an extent that it
is not possible for authors to introduce accessibility problems
Guideline
B.2.4 Assist authors to manage, edit, and reuse equivalent alternatives for non-text objects.
[Techniques]
[Return to Guideline]
Rationale: Improperly
generated equivalent alternatives can create accessibility problems
and interfere with accessibility checking.
@@http://lists.w3.org/Archives/Public/w3c-wai-au/2008JulSep/0083.html@@
B.2.4.1 Accept, Modify, Reject: Authors have
the opportunity to accept, modify, or reject any authoring tool-supplied equivalent
alternative, prior to insertion.
(Level A)
- Technique B.2.4.1-1 [Sufficient]: Providing a mechanism for the author to accept, modify, or reject any equivalent alternatives that the authoring tool supplies during the insertion process.
- Technique B.2.4.1-2 [Advisory]: Allowing the author to accept patterns of future uses of an equivalent alternative under certain conditions (e.g., whenever the same object is marked with the same semantic role).
- Technique B.2.4.1-3 [Advisory]: If the author changes the alternative equivalent for a non-text object,
asking the author whether all instances of the object with the same
known function should also be updated.
B.2.4.2 Edit Existing: If the authoring tool is capable of adding equivalent
alternatives for a type of non-text
objects then authors can edit the equivalent
alternatives.
(Level A)
- Technique B.2.4.2-1 [Sufficient]: Proving editing mechanisms for all applicable equivalent alternative types in a properties editor.
- Technique B.2.4.2-2 [Advisory]: Providing an editing capability for any equivalent alternatives managed by the tool.
- Example: A text equivalents registry viewer allows the author to query and edit the various text equivalents stored in the registry. For maximum flexibility, the design takes into account multiple non-text objects of the same name, multiple types of text equivalents for each non-text object, and multiple versions of each text equivalent type. In the viewer shown here, the author has selected "image" as the "media type" and then selected pic123.gif as the "object" to edit. This has brought up a rendering of the "earthrise" image. The viewer also shows that the object has three text labels. The author has selected one ("An earth rise as seen from the moon") in order to edit it. In addition some authoring tips are included ("Alternate text should be 10 words or less and should include any text in the image", "Image buttons should have alternate text that describes the button function.", and "Image bullets should have "bullet" as alternate text."(Source: mockup by AUWG)

B.2.4.3 Acceptable Sources: Authoring tools only supply equivalent alternatives from the following sources (Level AA):
- (a) Author-Entered: equivalent
alternatives previously entered by authors for
the same non-text
object (e.g., by the same author, or another author on
a collaborative system),
- (b) From Object Database: equivalent
alternatives stored with the non-text
object in an object database (or equivalent),
- (c) Null when Appropriate: null equivalent
alternatives for non-text
objects that are recognized by the authoring tool as only used for pure decoration, or
- (d) Audio, Video, or CART Analysis: automatic video or audio analysis (e.g., speech recognition).
- Technique B.2.4.3-1 [Sufficient]: Placing, within the appropriate field of the non-text object editing dialog box, a text alternative (or multiple alternatives if a drop-down is used) that was obtained from one of the acceptable sources.
B.2.4.4 Save for Reuse: Authors can store, for future reuse, both of the following author-assigned equivalent
alternatives (as applicable) (Level AAA):
- Technique B.2.4.4-1 [Sufficient]: Maintaining a registry
that associates object identity information with the text and URIs of alternative information (e.g., making use of the Resource Description Framework (RDF) [RDF10]). Whenever an object
is used and an equivalent alternative is collected, via prompting (see Guideline B.2.1)
or repair (see Guideline B.2.3) the object's identifying information and the alternative information is added to the registry. The stored alternative
information is presented back to the author as default text in the appropriate field, whenever
the associated object is inserted.
- Technique B.2.4.4-2 [Advisory]: Allowing several different versions of alternative information to be associated with a single object.
- Technique B.2.4.4-3 [Advisory]: Ensuring that the stored alternative information required
for pre-authored content (see Guideline B.1.5) is made interoperable with the management
system to allow the alternative equivalents to be retrieved whenever the
pre-authored content is inserted.
- Technique B.2.4.4-4 [Advisory]: Using the stored alternatives to support keyword searches of the object database (to simplify the task of
finding relevant images, sound files, etc.).
- Technique B.2.4.4-5 [Advisory]: Allowing the equivalents alternatives registry to be made shareable between authors in collaborative systems.
Note: Equivalent
alternatives should not be automatically generated from unreliable sources (e.g., file
names should not be used as text alternatives)@@.
Guideline B.2.5 Assist authors with accessible templates and other pre-authored content.
[Techniques]
[Return to Guideline]
Rationale: Templates and other pre-authored
content (e.g., clip art, synchronized media, widgets, etc.) that are not accessible impose additional repair tasks on authors.
B.2.5.1 Templates "A" Accessible: If the authoring tool automatically selects templates or pre-authored content, then the selection meets WCAG Level A when used. (Level A)
B.2.5.2 Provide Accessible Templates: If the authoring tool provides templates, then there are accessible template options for a range of template uses.
(Level A)
- Technique B.2.5.2-1
[Sufficient]: Ensuring all templates meet at least WCAG Level
A when used.
- Technique B.2.5.2-2 [Sufficient]: Ensuring that a reasonably representative set of templates is accessible.
- Example: A tool provides several template choices for home pages, guest books and on-line albums. For each type of functionality, the basic option is accessible.
B.2.5.3 Template Selection Mechanism: If authors are provided with a template selection
mechanism, then both of the following are true (Level A):
- (a) Indicate: the selection
mechanism indicates the accessibility status of templates (if known),
- (b) Prominence: any accessible template options have prominence that is comparable with that of other options in
the selection mechanism.
- Technique B.2.5.3-1 [Sufficient]: Listing the available templates and providing accessibility status as a sortable field.
- Technique B.2.5.3-2 [Advisory]: Storing the accessibility status within the template.
- Technique B.2.5.3-3 [Advisory]: Storing the accessibility status external to the template within a template management system.
- Technique B.2.5.3-4 [Advisory]: If suitable, evaluating templates for accessibility at run-time.
B.2.5.4 Templates "AA" Accessible: If the authoring tool automatically selects templates or pre-authored content, then the selection meets WCAG Level AA when used. (Level AA)
- See Techniques for B.2.5.1 using WCAG Level AA.
B.2.5.5 New Templates: If authors can use the authoring tool to create new templates for use by a template selection
mechanism, they have the option to record the accessibility status of the new templates.
(Level AA)
- See Techniques or B.2.5.3 for ways in which the status might be stored.
- Technique B.2.5.4-1 [Sufficient]: Providing a status saving option as part of the accessibility checking feature (see Guideline B.2.2).
- Technique B.2.5.4-2 [Advisory]: Making accessibility checks mandatory before saving templates.
- Technique B.2.5.4-3 [Advisory]: Advising the author that templates should be held to a high accessibility standard, since they will be repeatedly reused.
B.2.5.6 Templates in Repository: If the authoring tool provides a
repository of templates, then each of the templates has a recorded accessibility status.
(Level AA)
- See Techniques for B.2.5.3 for ways in which the status might be stored.
B.2.5.7 Pre-Authored Content Selection Mechanism: If authors are provided with a selection mechanism for pre-authored content other than templates (e.g., clip art gallery, widget repository, design themes), then both of the following are true (Level AA):
- (a) Indicate: the selection
mechanism indicates the accessibility status of the pre-authored content (if known),
- (b) Prominence: any accessible options have prominence that is comparable with that of other options in
the selection mechanism.
- See Techniques for B.2.5.3, reading "pre-authored content" in place of "templates".
- Technique B.2.5.7-1 [Advisory]: Ensuring that equivalent alternatives provided for pre-authored content are compatible with features to manage,
edit, and reuse equivalent alternatives (see Guideline B.2.4).
- Example: An authoring tool is shipped with a clip art collection. Each image in the collection has a short text label and long text description and the associations have all been pre-loaded into the equivalent alternative management system so that whenever the author inserts an image its equivalent alternatives are automatically retrieved.
B.2.5.8 Pre-Authored Content in Repository: If the authoring tool provides a repository of pre-authored content, then
each of the content objects has a recorded accessibility status. (Level AA)
- See Techniques for B.2.5.3 for ways in which the status might be stored.
B.2.5.9 Templates "AAA" Accessible: If the authoring tool automatically select templates or pre-authored content, then the selection meets WCAG Level AAA when used.
(Level AAA)
- See Techniques for B.2.5.1 using WCAG Level AAA.
Applicability Notes:
Templates may be complicated to check for accessibility due to their inherent incompleteness. The accessibility status of templates is instead measured by the accessibility of content (in the final technology) created through their proper use.
PRINCIPLE
B.3: Accessibility solutions must be promoted and integrated
Note: In addition to the normative requirements of
this principle, implementers should also consider close integration of features
that support accessible authoring with the "look-and-feel" of
other features of the authoring tool. This type of integration has the
potential to:
- produce a more seamless product;
- leverage the existing knowledge and skills of authors;
- make authors more receptive to new authoring requirements; and
- reduce the likelihood of confusion.
However, whenever new features are introduced into an authoring tool,
striking the right design balance between the similarity with existing
features and the provision of new functionality is often more of an art
than a science.
Guideline B.3.1
Ensure that accessible authoring
actions are given prominence.
[Techniques] [Return to Guideline]
Rationale: Some authors are
most likely to use the first and easiest authoring
action they encounter in the authoring tool user interface that
achieves their intended mainstream rendered outcome.
B.3.1.1 Accessible Actions Prominent (Minimum): If authors are provided with a choice of authoring actions to achieve the same mainstream rendered outcome, then actions that implement accessible
authoring practices are at least as prominent as the other action(s) (e.g., a "bold" button in a toolbar inserts semantic rather than formatting markup).
(Level A)
- Technique
B.3.1.1-1 [Sufficient]: Removing less accessible options.
- Technique
B.3.1.1-2 [Sufficient]: Providing the more accessible choice with a higher position in the menus and having it appear in interface shortcuts such as toolbars.
- Example: An authoring tool that supports
two methods for setting text color: using CSS and using
font
.
Since using CSS is the more accessible option, it is given a higher prominence
within the authoring interface by: (1) the "CSS Styling" option
appearing above the "FONT Styling" option in the drop down Text
menu, and (2) the CSS styling option being used to implement the one-click
text color formatting button in the tool bar. The association is made clear because the toolbar button has the same icon (an "A" beside a color spectrum) as the "Color" sub-menu item under the "CSS Styling" menu option.). An (Source: mockup by AUWG)

B.3.1.2 Accessible Actions Prominent (Enhanced): If authors are provided with a choice of authoring
actions to achieve the same mainstream rendered outcome, then actions that implement accessible
authoring practices are more prominent than the other action(s). (Level AA)
Guideline B.3.2 Ensure that sequential authoring processes integrate accessible
authoring practices.
[Techniques] [Return to Guideline]
Rationale: When accessibility considerations are a natural part of the workflow, they become a routine part of authoring.
B.3.2.1 Sequencing Features: Function that sequences authoring actions for authors (e.g., wizards) provide any accessibility prompts relevant to the content being
edited at or before the first opportunity to successfully complete
the function. (Level AA)
B.3.2.2 Sequenced Instructions: Instructions (e.g., tutorials,
reference manuals, design guides) that consist of a sequence of
steps for authors to follow include the relevant accessibility
authoring practices in the sequence before the first
opportunity to successfully complete
the sequence. (Level AA)
Guideline B.3.3
Ensure that features
of the authoring tool supporting the production of accessible content are available. [Techniques][Return to Guideline]
Rationale: The accessible
content support features will be more likely to be used if they are turned on and are afforded reasonable prominence within the authoring tool user interface.
- B.3.3.1 Active by Default: All accessible content support
features are active by default.
(Level A)
- Technique B.3.3.1-1 [Sufficient]: Ensuring that all accessible content support features are turned on by default within the authoring tool preferences area.
- Example: The preference setting area of an authoring tool, open to an "Accessibility" section, shows the default settings. "W3C-WCAG" and a level (e.g. "Double-A") are selected as are the following options: "Check accessibility as you type", "Check accessibility after saving", "Auto-correct when possible", "Highlight accessibility related fields", "Prompt when highlighted fields are left blank", and "Provide accessibility 'Quick Tips'". (Source: mockup by AUWG)

- B.3.3.2 Reactivate Option: If authors deactivate
an accessible
content support feature, then they can always
reactivate the feature.
(Level A)
- Technique B.3.3.2-1 [Sufficient]: Providing an authoring tool preferences area where any deactivated features can be reactivated.
- B.3.3.3 Deactivation Warning: If authors deactivate
an accessible content support feature, then the authoring tool informs
them that this may increase the risk of content accessibility problems.
(Level AA)
- Technique B.3.3.3-1 [Sufficient]: Providing the author with a warning whenever an accessible content support feature is turned off (e.g., from the authoring tool preferences area.
- Example: In an authoring tool, the author has unchecked a "highlighting accessibility
related fields" feature the tool. As a result the tool displays a warning that reads "You have just
turned off the highlighting accessibility related fields feature. This feature
is designed to inform you when information must be provided in order for
your documents to comply with your target accessibility setting. Turning
this feature off could cause your documents to be less accessible to many
users. In some jurisdictions accessibility is a legal requirement. Are you
sure you want to proceed?". The author has the option to answer "Yes", "No" or "Cancel". (Source:
mockup by AUWG)
- B.3.3.4 At Least as Prominent: Accessible content support features are at least as prominent to authors as
comparable features related to other types of
Web content problems (e.g., invalid markup, syntax errors, spelling
and grammar errors).
(Level AA)
- Technique B.3.3.4-1 [Sufficient in combination]: Ensuring that prompting for accessibility information
has the same prominence as prompting for information critical to content correctness (e.g., a tool that prompts the author for a required multimedia file name attribute has prompts with the same prominence
for short text labels and long descriptions for that object.
- Example: An "Image Properties" dialog box in which the input fields
are ordered (from top to bottom, left to right): source ("src"), short label ("alt"), long description ("longdesc"), height, and width. The buttons at the bottom are "More...", "OK" and "Cancel". (Source: mockup by AUWG)

- Technique B.3.3.4-2 [Sufficient in combination]: Ensuring that utilities for checking and repairing accessibility problems
has the same prominence as utilities for checking for information critical to content correctness (e.g., a tool that checks for spelling, grammar, or code syntax will
have checks with the same prominence as checking for accessibility problems).
Example: An authoring interface that checks
for and displays spelling and accessibility errors with the same prominence in that both are shown as underlines, one red, one blue.
In this case, the author has activated a right-click pop-up menu on the word "CHZ" that includes
spelling repair options ("1 Khz", "2 Chi", "Check Spelling...") and accessibility repair options ("Repair: Set acronym expansion…", "Skip", "Ignore", and "Check Accessibility...") and "Help...". (Source: mockup by AUWG)

- Technique B.3.3.4-3 [Sufficient in combination]: Ensuring that documentation for accessibility has the
same prominence as documentation for information critical to content correctness.
(e.g., a tool that documents any aspect of its operation will have documentation
with the same prominence for accessibility).
- Example: Accessibility documentation
is part of the main documentation of an authoring tool, with very similar prominence
to that of the spelling-related features. In the right pane is the documentation table of contents, where "Accessibility Features" appears as a top level topic just below "Spelling Features". In the left panel is the help text, demonstrating a style typical of the rest of the help system: "Checking for Accessibility: A variety of accessibility checking options are available: Accessibility verifier, Check accessibility as you type, Manual test support materials.
These are suitable for use at different times during the authoring process and all have options that can be changed with the accessibility preferences. To get more information on accessible Web content, see the References.". (Source: mockup by AUWG)

Guideline B.3.4
Ensure that features
of the authoring tool supporting the production of accessible
content are documented. [Techniques][Return to Guideline]
Rationale: Without documentation of
the features
that support the production of accessible content (e.g., prompts
for alternatives, accessibility checkers), some authors may
not be
able to find or use them.
B.3.4.1 Instructions: Instructions for using
the accessible content support features appear in the documentation.
(Level A)
- Technique B.3.4.1-1 [Sufficient]: Ensuring that the help system answers
the question "What features of the tool encourage the production
of accessible content?" with reference to all of the accessible content support features and for each feature identified, the help system answers the question "How are these features operated?".
- Technique B.3.4.1-2 [Advisory]: Providing direct links from accessible content support features to context sensitive
help on how to operate the features.
- Technique B.3.4.1-3 [Advisory]: Providing direct links from within the accessibility-related documentation that take the author directly to the relevant accessible content support features.
- Technique B.3.4.1-4 [Advisory]: During prompting and repairs, providing the author
with immediate access to some basic accessibility documentation and one-step
access to more comprehensive documentation.
- Example: An accessibility
checker includes some limited tips for authoring short text labels listed beneath the
text entry area as well as a "Help" button linking to the full documentation. The tips are: "Alternate text should be 10 words or less and should include any text in the image.", "Image buttons should have alternate text that describes the button function.", and "Image bullets should have 'bullet' as alternate text.". The screen shot also includes the name of the problem ("Missing Alternate Text Label for an Image"), a field for adding the short text label and a preview rendering of the image ("earthrise"). At the bottom are five buttons: "Help", "< Back", "Repair", "Skip", and "Cancel". (Source:
mockup by AUWG)

B.3.4.2 Accessible Authoring Tutorial: A tutorial on the accessible
authoring process that is specific to the authoring tool is provided.
(Level AAA)
- Technique B.3.4.2-1 [Sufficient]: Providing a tutorial that describes how to use the authoring tool to increase the accessibility of Web content. The tutorial begins at the typical starting point for the tool (e.g., empty document) and, for example, describes how accessibility prompting should be followed as content is being added or modified. The tutorial also covers when and how checking and repair should be performed.
- Technique B.3.4.2-2 [Advisory]: Ensuring that wherever rationales appear, the text avoids referring to accessibility features
as being exclusively for particular groups (e.g., "for blind authors"). Instead, the rationales emphasize the importance of accessibility
for a wide range of content consumers, from
those with disabilities to those with alternative viewers (see "Auxiliary
Benefits of Accessibility Features", a W3C-WAI resource).
- Technique B.3.4.2-3 [Advisory]: Providing a dedicated accessibility
section.
- Technique B.3.4.2-4 [Advisory]: Providing context-sensitive help definitions for accessibility-related terms.
- Technique B.3.4.2-5 [Advisory]: Including pointers to more information on accessible Web authoring, such as WCAG and other accessibility-related resources.
- Technique B.3.4.2-6 [Advisory]: Including pointers to relevant technology specifications. This is particularly relevant for languages that are easily hand-edited, such as most XML languages.
- Technique B.3.4.2-7 [Advisory]: Calling author attention to accessibility-related idiosyncrasies of the tool compared to other authoring tools that create the same kind of content.
- Example: Content might need to be saved before an automatic accessibility checking feature becomes active.
Guideline B.3.5
Ensure that any authoring practices demonstrated in documentation are
accessible. [Techniques] [Return to Guideline]
Rationale: Demonstrating
accessible authoring as routine practice will encourage its acceptance by some authors.
B.3.5.1 Model Accessible Practice (Minimum): Any examples of authoring practices in the documentation (e.g.,
markup, screen shots of WYSIWYG
editing views) demonstrate WCAG Level
A accessible
authoring practices.
(Level AA)
- Technique B.3.5.1-1 [Sufficient]: Ensuring that in the authoring tool documentation, all examples of content conform to WCAG Level
A and also that all screen shots of the authoring tool interface are in states that corresponds with the production of content that conforms to Level A (e.g., prompts filled in, optional accessibility features turned on, etc.).
Example: Documentation for
the input
element in this instruction-level authoring tool makes use
of the label
element in an example in order to reinforce the routine nature
of the pairing. The help text reads: "Input Element: Input elements are form controls. They let the reader of your page use text entry, checkboxes, radio buttons, etc. to interact with your page. The most important attribute of the INPUT element is type. The value of type can be: button, checkbox, file, hidden, image, password, radio, reset, submit, and text. Examples:<label>Enter your name: <input type="text" name="name" maxlength="30"></label><input type="submit">
. (Source: mockup by AUWG)

- Technique B.3.5.1-2 [Advisory]: Ensuring all examples of content pass the authoring tool's own accessibility checking mechanism (see Guideline B.2.2).
- Technique B.3.5.1-3 [Advisory]: Ensuring that the documentation includes at least
one model of a wide range of WCAG Level
A accessible
authoring practices.
- Technique B.3.5.1-4 [Advisory]: Ensuring plug-ins that update the accessibility features
of a tool also update the documentation examples.
B.3.5.2 Model "AA" Accessible Practice (Enhanced): Any examples of authoring practices
in the documentation demonstrate WCAG Level AA accessible
authoring practices.
(Level AAA)
- See Techniques for B.3.5.1 using WCAG Level AA.
Applicability Notes:
An exception to these success criteria is allowed for examples that are specifically intended to demonstrate inaccessible practices to be avoided.
Appendix A: Prompting for Various Types of Accessibility Information:
This list is representative, but not necessarily complete.
1. Prompting and assisting for short text labels (e.g., alternate text, titles,
short text metadata fields, rubies for ideograms):
- (a) Prompts for short text strings may be given relatively little
screen real estate because they are usually intended to elicit entries
of ten words or less. (see Example
A-1a)
- (b) Provide a rendered view of the object being labeled, while the author is composing the label. (see Example
A-1a)
- (c) Provide the option of automatically retrieving previously used labels. (see Example
A-1a, Guideline B.2.4)
- (d) Detect objects
serving special functions and offer standard labels for them (e.g., "decorative", "button",
"spacer", "horizontal rule", etc.).
- (e) If the tool offers the author previously used labels or special
function label text (see (c)) then editable text entry boxes with drop-down lists should be used to allow the author the option of entering different text (see Example
A-1a).
- (f) In code-based tools, prompt the author with short text labels that are already marked up appropriately (see
Example A-1b).
Example A-1a: A dialog box offers short text labels for reuse. It shows an "Insert Image" dialog box a thumbnail image of the "earthrise" graphic along with entry fields for "src", "alt", "longdesc", "height" and "width". The "alt" entry field is drop-down list that is shown with
several short labels for the same image. The first is a visual description in English ("An earth rise as seen from the moon"), the second is a visual description in French ("Une vue do la terre de la lune") and the third is an English functional label used if the image serves as a link ("Go to pictures of the earth").
(Source: mockup by AUWG)

Example A-1b: A instruction-level authoring interface offers short text labels for reuse. It shows the author midway through adding markup for an image. After adding the src
attribute value the author has pressed the spacebar, causing the tool to prompt them with the alt
attribute along with several attribute values, including a visual description in English (alt="An earth rise as seen from the moon"), a visual description in French (alt="Une vue de la terre de la lune") and an English functional label used if the image serves as a link (alt="Go to pictures of the earth"). (Source: mockup by AUWG)

2. Prompting and assisting for multiple text labels (e.g., image map area labels):
- (a) Prompts for multiple text labels may be similar to those for short
text labels, with allowance made for rapidly adding several labels (e.g. a spreadsheet type of control). (see Example
A-2)
- (b) Provide a rendered view of the various objects being labeled, while the author is composing the labels. (see Example
A-2)
- (c) If the objects have URIs (e.g. image map areas), display these as a hint for the labels. (see Example
A-2)
- (d) If the objects have URIs (e.g. image map areas), offer to automatically generate a set of plain text links from the
labels that the user completes. (see Example
A-2)
Example A-2: An authoring interface that prompts for image
map area text labels. It is comprised of a list with two columns.
In the right-hand column is the URL for each image map area. This can
be used as a hint by the author as they fill in the text labels (left-hand
column). A checkbox at the bottom provides the option of using the text
labels to create a set of text links below the image map. (Source: mockup
by AUWG)

(3):
Prompting and assisting for long text descriptions (e.g., longdesc text,
table summaries, site information, long text metadata fields):
- (a) Begin by prompting the author as to whether the inserted object
is adequately described with an existing short text label. Providing a
view of the page with rendering of the object turned off may help the author decide. (see
Example A-3)
- (b) If the short text label is determined to be inadequate, prompt the author for the
location of a pre-existing description. (see
Example A-3)
- (c) If the author needs to create a description, provide a special writing
utility that includes a rendered view of the object and description writing
advice.
- (d) Implement automated routines that detect and ignore some objects
that do not require long text descriptions (e.g., bullets, spacers, horizontal
rules).
Example A-3: An authoring interface that prompts for long text descriptions. A "description required" checkbox controls whether the rest of the interface is available. If a description is required, the author then has the choice of opening an existing description file or writing (and saving) a new one. If they choose to use an existing file, there is a text entry area for the name along with a button to browse the file system. If they choose to compose a new description, there is a text entry area for the description followed by a text field for the file name and a button to save it to that location. In the situation shown, the author chooses to use an existing description of "earthrise" so the file name containing the description is shown. In addition, the text of the description from the file is loaded into the compose area ("The earth hangs in the pitch black sky above the gray horizon of the moon. The dazzling blue sphere is covered with creamy white streamers of cloud.") in case the author would like to use this text as a basis for a new description. (Source: mockup by AUWG)

(4):
Prompting and assisting for form control labels:
- (a) Prompts for form controls may be similar to those for short text labels and/or multiple text labels.
- (b) For formats in which form control labels are external to the actual form control elements (e.g. HTML), allow the author to either directly add a form control label or identify pre-existing text
strings that are already serving implicitly as labels.
- (c) It may be helpful to render the form controls with indicators of label associations or missing labels.
- (d) It may be helpful to redisplay the controls in spreadsheet form to assist the author in determining author which controls are lacking labels. (see
Example A-4)
Example A-4: A form properties list
with five columns that allows the author to simultaneously decide the following for each field: the tab
order, form name, field label, control type, and accesskey. In this example, two form
field labels are missing, causing prompts (yellow highlighting of the cells and red icons) to be displayed. "Move up" and "move down" buttons are provided. (Source: mockup
by AUWG)

(5):
Prompting and assisting for form field place-holders:
- (a) Prompts for form field place-holders may be similar to those for short text labels, multiple text labels, and/or form control labels.
- (b) Provide authors with the option of directly selecting nearby text
strings that are serving implicitly as labels and use the text as place-holders.
(6): Prompting
and assisting for TAB order sequence:
- (a) At the very least, provide a field for entering the TAB order number for any element that can appear in the TAB order.
- (b) Manage the TAB order to prevent duplicate TAB indices and to reduce the need for manual renumbering.
- (c) Provide contextual information to supplement the basic TAB order numbers, such as the label or name of controls.
- (d) Provide the author with a point-and-click numbering tool that they can use to select
controls to quickly create a TAB order.
- (e) Provide a list of links and controls to check the TAB order.
- (f) Where there are only a few links that change in each page of a collection, ask the author to confirm whether these links receive focus first. If so, then the tool can appropriately update the tabindex order.
(7):
Prompting and assisting for navigational shortcuts (e.g., keyboard shortcuts,
skip links, voice commands, etc.):
- (a) Prompt authors to add skip-over navigation links for sets of common
navigation links.
- (b) Prompt authors with a list of links that are candidates for accesskeys,
because they are common to a number of pages in a site.
- (c) Manage accesskey lists to ensure consistency across sites and to
prevent conflicts within pages. (see Example
A-7)
Example A-7: A instruction-level authoring interface
that suggests access key values. The following markup can be seen: "<body><p>Here is one of the most famous photographs taken from the <a href="moon.html" > moon.</a></p><It was taken with a special <a href=camera.html" accesskey="c">camera.</p>"
. A pop-up menu, centered on the word "moon" suggest accesskey="moon", because "moon" begins with "m", followed by the rest of the alphabet in order. Accesskey="c" is missing, however, since it is already
used as an accesskey later in the document (for the "camera" link).
(Source: mockup by AUWG)

(8):
Prompting and assisting for contrasting colors:
- (a) Assemble color palettes with insufficiently contrasting colors excluded
or identified. (see Example A-8)
- (b) To help the author test the contrast, provide gray scale and black and white views or suggest that the author
activate the operating system high contrast mode.
- (c) Emphasize "Web-safe" colors.
Example A-8: A dialog box for choosing sufficiently contrasting color combinations. The dialog box has two tabs: one for text color and one for background color. A "hide low contrast choices" checkbox has been selected, so the palette of colors has been pre-screened
so that sufficient contrast between the text and the current background
color is assured. All other colors have been grayed out. (Source:
mockup by AUWG)

(9):
Prompting and assisting for alternative resources for multimedia (transcripts,
captions, video transcripts, audio descriptions, signed translations, still
images, etc.):
- (a) Prompt the author for the location of pre-existing alternative
resources for multimedia.
- (b) Provide a single utility where the various alternative resources can be managed at the same time.
- (c) Although producing alternative resource for multimedia can be a
complex process for long media files, production suites do exist or authoring
tools can include simple utilities, with built-in media players, for producing
simple alternative resources.
- (d) The tool should make an attempt to access existing alternative resources for multimedia,
which may be incorporated into media (e.g., as text or secondary audio tracks) or be located separately but nearby within content.
(10):
Prompting and assisting for metadata:
- (a) For metadata information fields requiring information similar to
that discussed in the other sections of this technique, see the relevant
section. For example: short text labels, long text descriptions, and alternative resources for multimedia.
- (b) When prompting for terms in a controlled vocabulary, allow the author
to choose from lists to prevent spelling errors.
- (c) Provide the option of automating the insertion of information that
easily stored and reused (e.g., author name, author organization, date,
etc.).
- (d) Automate metadata discovery where possible.
- (e) Provide the option of storing licensing conditions within metadata
(e.g., by Creative Commons licenses, GPL, BSD, etc.)
- (f) Consider characterizing accessibility of content using IMS AccessForAll
Meta-data Specification [ACCESSFORALL] to facilitate personalized content delivery.
(11):
Prompting and assisting for document structure:
- (a) Alert the author to the occurrence of unstructured content in a way
that is appropriate to the workflow of the tool.
- (b) Provide the author with options for creating new content that is structured,
such as:
- templates (with pre-defined structure),
- wizards (that introduce structure to content through a series of
system-generated queries), or
- real time validators (that may be set by the author to prevent the
creation of improperly structured content)
- (c) Provide the author with options for imposing structure on existing unstructured
content.
- For tools that support explicit structural mechanisms offer authors
the opportunity to use those mechanisms. For example, for DTD or schema
based structures, provide validation in accordance to the applicable
DTD or schema.
- For tools that do not support explicit structural mechanisms, offer
authors the option of deriving structure from format styles. For example,
provide authors a mechanism to map presentation markup that follows
formatting conventions into structural elements. For example, patterns
of text formatting may be interpreted as headings (see
Example A-11) and multiple lines of text beginning items
with certain typographical symbols, such as "*" or "-",
may be interpreted as list items.
- (d) Provide structure-based editing features, such as:
- hide/show content blocks according to structure,
- shift content blocks up, down, and sideways through the document
structure, or
- hierarchical representation or network diagram view of the document
structure, as appropriate.
- (e) Provide fully automated checking (validation)
for structure.
- (f) Provide fully automated or semi-automated repair for structure.
- (g) It is not necessary to prohibit editing in an unstructured mode. However,
the tool should alert authors to the fact that they are working in an
unstructured mode.
Example
A-11: A WYSIWYG authoring tool that detects opportunities
for enhancing structure and alerts the author. On the left side is the WYSIWYG editing view with the title of the page ("Mars") displayed with a blue underline. The author has brought up a pop-up menu for the title and sees the following options: "Repair: Mark as heading (a sub-menu displays the different levels of header (i.e., h1, h2, etc.)) for the author to choose", "Skip", "Ignore", "Check Accessibility...", and "Help...". On the right, an element inspector makes clear that the title is currently marked up as a paragraph. (Source: mockup by AUWG)

(12):
Prompting and assisting for tabular structure:
- (a) Prompt the author to identify tables as used for layout or data
or implement automated detection mechanisms.
- (b) Differentiate utilities for table structure from utilities for document
layout - use this when tables are identified as being for layout.
- (c) Prompt the author to provide header information. (see
Example A-12)
- (d) Prompt the author to group and split columns, rows, or blocks of
cells that are related.
- (e) Provide the author with a linearized view of tables (as tablin does).
Example A-12: A WYSIWYG authoring tool that
prompts the author to decide whether the top row of a table contains the table
header cells. The top row of the rendered table is outlined in blue to indicate an accessibility problem. The author has brought up a pop-up menu for one of the cells in the top row and sees the following options: "Repair: Set as header row", "Skip", "Ignore", "Check Accessibility...", and "Help...". (Source: mockup by AUWG)

(13):
Prompting and assisting for style sheets:
- (a) Use style sheets, according to specification, as the default mechanism
for presentation formatting and layout.
- (b) If content is created with a style sheet format, along with a content
format, the use of that style format must also meet the requirements of
WCAG.
- (c) Conceal the technical details of style sheet usage to a similar
degree as for usage of other markup formats supported by the tool.
- (d) Assist the author by detecting structural markup (e.g., header tags, etc.) that has been misused
to achieve presentation formatting and, with author permission, transforming
it to use style sheets. (see Example A-13)
- (e) Prompt the author to create style classes and rules within and across
document, rather than using more limited in-line styling.
- (f) Assist the author by recognizing patterns in style sheet use and
converting them into style classes and rules.
- (g) Provide the option of editing text content independently of style
sheet layout and presentation formatting. (see
Example A-13)
- (h) Assist the author with the issue of style sheet browser compatibility
by guiding them towards standard practices and detecting the existence
of non-standard practices.
- (i) Assist the author by providing a style sheet validation function.
- (j) Maintain a registry of styles for ease of re-use.
- (k) For prompting and assisting with specific types of information required
by style sheets, see the other sections in this technique. For example:
font/background colors (see (8)) and document structure (see (12)).
- (l) Consult the following references: Accessibility Features of CSS [CSS2-ACCESS] and XML languages [XAG].
Example A-13: A WYSIWYG authoring tool that indicates to the author that
a heading has been misused to indicate emphasis. In the WYSIWYG editing view, some text ("VERY HOT") is rendered large and bold because it has been improperly marked as a heading and it is therefore marked with a blue underline as an accessibility problem. The author has brought up a pop-up menu for the text and sees the following options: "Repair: Mark with style (a sub-menu displays the different styles available: .bodytext, .quotetext, .hot_emphasis, .cold_emphasis)", "Skip", "Ignore", "Check Accessibility...", and "Help...". (Source: mockup by AUWG).
(14): Prompting
and assisting for clearly written text:
- (a) Prompt the author to specify a default language of a document.
- (b) Provide a thesaurus function.
- (c) Provide a dictionary lookup system that can recognize changes of
language, terms outside a controlled vocabulary as well as known abbreviation
or acronym expansions.
- (d) Provide an automated reading level status. (see
Example A-14a)
- (e) Prompt the author for expansions of unknown acronyms, recognizable
in some languages as collections of uppercase letters. (see Example
A-14b)
Example A-14a: A instruction-level authoring
interface that indicates the reading level of a page and whether it exceeds
a limit determined by the author's preference settings. The code view includes the following markup: <body><h1>Mars</h1><p>Mars is the fourth planet in the solar system, orbiting at a distance of 1.5 AU, with a period of 687 days.</p></body></html>
. Then in a status bar below the text entry area, is a reading level display: "Reading Level: 11.2 (target<8)". The 11.2 is highlighted with a yellow background and bold text to indicate that the target is exceeded. (Source: mockup
by AUWG)
Example
A-14b: An authoring interface
that prompts the author to enter an acronym expansion. The rendered text reads: "The 'habitable zone' around a star is the region of that star’s solar system in which liquid water is possible. The continuous habitable zone (CHZ) is the region of the solar system which has remained in the zone, even during changes in the star’s radiation pattern." The acronym "CHZ" is identified with a blue underline as an accessibility problem. The author has brought up a pop-up menu for the acronym and sees the following options: "Repair: Enter acronym expansion…", "Check Accessibility...", and "Help...". (Source: mockup by AUWG)
(15): Prompting
and assisting for device independent handlers:
- (a) During code development, prompt the author to include device-independent
means of activation.
- (b) Prompt authors to use device-independent events (e.g., DOM 2
onactivate
[DOM]) instead of device-specific events (e.g., onclick
),
or route multiple events (onclick
and onkeypress
)
through the same functions.
- (c) Prompt authors to add a DOM
onfocus
event to elements
that are targeted with the onmouseover
event.
- (d) Prompt authors about using events for which no common device-independent
analogue exists (e.g.,
ondblclick
) and avoid these events
as default options.
(16):
Prompting and assisting for non-text supplements to text:
- (a) Prompt the author to provide icons for buttons, illustrations for
text, graphs for numeric comparisons, etc. (see
Example A-16)
- (b) Where subject metadata is available, look up appropriate illustrations.
- (c) If the author has identified content as instructions then provide
templates or automated utilities for extracting flow charts, etc.
Example A-16: An authoring
interface for prompting the author about whether a paragraph that contains
many numbers might be made more clear with the addition of a chart or
graph. On the left side of the interface is the rendered text: " Planet Orbits: The inner planets orbit the sun relatively quickly with Mercury orbiting the sun in 88 days, Venus in 224 days, Earth in 365 days, and Mars in 687 days. Compare this to Jupiter’s, 4332 day orbit." This text is marked with a yellow exclamation mark icon. On the right side is the following explanation of the error icon: "This paragraph contains 5 numbers. Would readers benefit if a chart or graph of this information was added?". "Yes" and "no" buttons are provided. (Source: mockup by AUWG)

(17): Prompting and assisting the author to make use of up-to-date technologies:
- (a) Default to the most up-to-date technologies available whenever the author
has not specified a technology.
- (b) Give up-to-date technologies a higher prominence during
technology selection.
- (c) Provide tools that convert content in older technologies into more up
to date ones.
- (d) Fully or partially automate some of the more complex aspects of
more up to date technologies, including document structure (see (11))
and use of style sheets (see (13)).
Appendix B: Levels of Checking Automation
This list is representative, but not necessarily complete.
(a) Automated Checking:
In automated checking, the tool is able to check for accessibility problems
automatically, with no human intervention required. This type of check is
usually appropriate for checks of a syntactic nature, such as the use of
deprecated elements or a missing attribute, in which the meaning of text
or images does not play a role.
Example B-1: A summary interface for a code-based
authoring tool that displays the results of an automated check. The display is a tree-view where the leftmost nodes are the names of errors ("Image missing alternate text" and "Text boxes missing labels) with number of errors appended (e.g., "[6]") and the sub-items are the problem instances with line numbers appended (e.g., "(Line:45)"). (Source:
mockup by AUWG)

Example B-2: A WYSIWYG interface that displays the
results of an automated check in a WYSIWYG authoring view using blue
highlighting around or under rendered elements (in this case, the "earthrise" image and some "blinking text"), identifying accessibility
problems for the author to correct. (Source: mockup by AUWG)

Example B-3: An authoring interface of an
automated check in a instruction-level authoring view. The text is: "<body><p>Image:</p><img href="pic123.gif"/><hr/><blink>Blinking text</blink></body></html>
".In this view, the text
of elements with accessibility problems (img
and blink
) is shown in a blue font, instead
of the default black font. (Source: mockup by AUWG)

(b) Semi-Automated Checking:
In semi-automated checking, the tool is able to identify potential problems,
but still requires human judgment by the author to make a final decision
on whether an actual problem exists. Semi-automated checks are usually most
appropriate for problems that are semantic in nature, such as descriptions
of non-text objects, as opposed to purely syntactic problems, such as missing
attributes, that lend themselves more readily to full automation.
Example B-4: A dialog box that appears once
the tool has detected an image without a description attribute. However,
since not all images require description, the author is prompted to make
the final decision ("Does this image require descriptive text?"). The author can confirm the at this is indeed an accessibility
problem by choosing and move on to the repair stage by choosing "Yes" or press "No" to mark the potential problem, as not a problem at all. Additional help is available in the form of a tip: "An image requires descriptive text when the information it contains cannot be conveyed in 10 words or less using an alternate text label." (Source:
mockup by AUWG)

(c) Manual Checking:
In manual checking, the tool provides the author with instructions for detecting
a problem, but does not automate the task of detecting the problem in any
meaningful way. As a result, the author must decide on their own whether
or not a problem exists. Manual checks are discouraged because they are
prone to human error, especially when the type of problem in question may
be easily detected by a more automated utility, such as an element missing
a particular attribute.
Example B-5: A dialog box that reminds the
author to check if there are any words in other languages in the document with the message: "Does this document contain any words or phrases in a different language than the main content?".
The author can move on to the repair stage by pressing "Yes" or press "No" to mark the potential problem, as not a problem at all.
(Source: mockup by AUWG)

Appendix C: Levels of Repair Automation
This list is representative, but not necessarily complete.
(a) Repair Instructions:
In manual repairing, the tool provides the author with instructions for making the necessary correction, but does not automate the task in any substantial way. For example, the tool may move the cursor to start of the problem, but since this is not a substantial automation, the repair would still be considered "manual". Manual correction tools leave it up to the author to follow the instructions and make the repair by themselves. This is the most time consuming option for authors and allows the most opportunity for human error.
Example C-1: Repair instructions in a code level editing view. In this case, the following markup is being edited: <body><p>Image:</p><img href="pic123.gif"/><hr/><blink>Blinking text</blink></body></html>
. Since the problems have already been detected in the checking step and the selected offending elements in a code view (<img href="pic123.gif"/>
and <blink>Blinking text</blink>
) have been highlighted in blue text. When the author puts focus on the highlighted text, a short repair instruction ("Repair: Add 'alt' attribute") appears in a status bar with a button than will open a longer explanation in the help system. (Source: mockup by AUWG)

(b) Semi-Automated:
In semi-automated repairing, the tool can provide some automated assistance to the author in performing corrections, but the author's input is still required before the repair can be complete. For example, the tool may prompt the author for a plain text string, but then be capable of handling all of the markup required to add the text string to the content. In other cases, the tool may be able to narrow the choice of repair options, but still rely on the author to make the final selection. This type of repair is usually appropriate for corrections of a semantic nature.
Example C-2: A semi-automated repair in a WYSIWYG editing view. The author has right-clicked on an image of the "earthrise" that has been highlighted with a blue outline by the automated checker system. This has brought up a pop up menu with the following choices: "Repair: Set Alt -Text: 'An earth rise as seen from the moon'",
"Enter different alt-text…", "
Skip", "Ignore", "Check Accessibility...", "Help...". The author must decide whether the label text that the tool suggests is appropriate. Whichever option the author chooses, the tool will handle the details of updating the content. (Source: mockup by AUWG)

(c) Automated:
In automated repairing, the tool is able to make repairs automatically, with
no author input required. For example, a tool may be capable of automatically
adding a document type to the header of a file that lacks this information.
In these cases, very little, if any, author notification
is required. This type of repair is usually appropriate for corrections
of a syntactic or repetitive nature.
Example C-3: An announcement
that an automated repair has been completed ("All instances of <blink> have been replaced with CSS styling according to your preferences."). The author selects an "ok" to proceed. An "undo" button
is provided in case the author wishes to reverse the operation. In some
cases, automated repairs might be completed with no
author notification at all. (Source: mockup by AUWG)

Appendix D: Author Interruption Timing Options
This list is representative, but not necessarily complete.
(a) Negotiated Interruption: A negotiated interruption is caused by interface mechanisms (e.g., icons or highlighting of the element, audio feedback) that alert the author to a problem, but remain flexible enough to allow the author to decide whether to take immediate action or address the issue at a later time. Since negotiated interruptions are less intrusive than immediate or scheduled interruptions, they can often be better integrated into the design workflow and have the added benefit of informing the author about the distribution of problems within the document. Although some authors may choose to ignore the alerts completely, it is not recommended that authors be forced to fix problems as they occur. Instead, it is recommended that negotiated interruption be supplemented by scheduled interruptions at major editing events (e.g., when publishing), when the tool should alert the author to the outstanding accessibility problems.
Example D-1: A WYSIWYG editing view makes the author of problems detected automatically by means of a blue line under text or around rendered objects with accessibility problems. Here, red lines are also visible, highlighting spelling errors in the text. The author can decide to address the problems at a later time. (Source: mockup by AUWG)

(b) Scheduled Interruption: A scheduled interruption is one in which the author has set the tool to alert them of accessibility issues on a configurable schedule. One option for the schedule might be to have prompts associated with the interface mechanisms for significant authoring events, such as opening, saving, closing, committing, or publishing files. At the significant authoring event, the author would be informed of the problem, while at the same time they would not be prevented from saving, publishing, printing, etc. A potential downside of postponing corrective actions is that by the time the prompt is displayed, the author may not have sufficient time or inclination to make the required changes, especially if they are extensive.
Example D-2: A "Publish" dialog box allows the author to publish multiple files at once, however in the case shown here, two of the files have uncorrected accessibility errors which causes them not to meet a "standard of publishing" the author has set for themselves in the options. As a result the files are selected, a message is displayed ("The selected files do not meet your specified standard for publishing.") and the "publishing" button is grayed out. This standard is referred to generally since it is assumed that it might include spelling and grammar standards as well as accessibility issues. (Source: mockup by AUWG)

(c) Immediate Interruption: An immediate interruption is the most intrusive timing option because the attention of the author is actively diverted from the current editing task by the notification of some issue. This might be achieved, for instance, by an alert dialog. This type of alert presents multiple usability problems and should be used sparingly because it interferes with the normal design workflow. Intrusive warnings are probably only appropriate when the window of opportunity for correcting a serious accessibility problem is about to close, such as when an author decides to publish the content in question. In general, negotiated and scheduled interruptions are preferred.
Example D-3: A modal dialog box contains the message: "This image is missing alternate text". The author must press the "OK" button to continue. (Source: mockup by AUWG)

Appendix E: Real-Time Content Production
Dealing flexibly with real-time content production. When authoring tools produce content in real time, it is usually no longer possible to delay addressing accessibility problems until an arbitrary point in the future. At the same time, due to the time pressure, authors in real-time environments tend to be less receptive to intrusive prompts. Nevertheless, tools that allow this kind of authoring should still take accessibility issues into account by supporting the following:
(a) Determination of Participant Requirements: If real-time authoring is consumed by individuals with no special communicative needs, there may be no need for real-time prompting. However, as with any other Web content it is often impossible for the author to know all of the needs of the actual or potential participants. Therefore, the best practice is to create real-time content that conforms with WCAG to the greatest extent possible. However, when this is not possible, a real-time authoring tool might be able to facilitate graceful degradation of accessibility by polling the participants (see "Request whiteboard descriptions" checkbox in the figure) or in some cases checking the profiles of participants (e.g., using CCPP, ACCLIP) to determine which types of accessibility practices would offer the greatest advantage in the short time available. Once this information is compiled, the tool can prompt the author (or see Assistant/Peer Author) to correct problems appropriately (preferably during Preparation Time). When it is not possible to know, with certainty, the needs of all participants, the tool should still assume that accessible content is required. This is especially true if the results of the session will be archived.
(b) Assistant/Peer Author: In some cases, it may be possible to designate one or more secondary authors in the live community, who can receive and respond to prompts for supplemental information generated as the primary author proceeds uninterrupted. The secondary author might be an unrelated specialist, analogous to Sign language interpreter, a co-author (helpful for describing technical drawings, etc.), or in some situations any member of the session audience (i.e., a peer).
(c) Preparation Time: If the authoring tool allows the author time to pre-assemble materials for a live presentation (e.g., a professor preparing for an online class), this authoring is not considered real-time authoring. The authoring tool has the opportunity and the obligation to support accessible authoring as described elsewhere in this document.
(d) Archiving: If the session will be archived, there may be other opportunities to increase the accessibility of the content of the archive by guiding the author through a process to check for and repair accessibility problems after the real-time session has ended, but prior to archiving.
If it has been determined that the author must provide real-time supplements, but no preparation time or assistant author are available, then in addition to allowing the author control of the nature and timing of prompting, the authoring tool can facilitate the inclusion of supplements by:
- Implementing the management functionality for equivalent alternatives (see Guideline B.2.4). This way, if the author uses an object that has been used before, the tool can suggest the previously stored alternative, which the author can quickly accept or decline without substantial workflow disruption.
- Providing a voice recognition capability so that the author's real-time speech input can be converted into captioning.
Example E-1: A real-time presentation in a whiteboard/chat client environment that has been enhanced to provide real-time descriptions. The example has five panes. On the far left is a list of participants ("Presenter", "John (You)", "Jane", and "Alice"). In the upper-middle is the chat "Presenter> I suggest a space theme for the slide presentation.", "Image File Inserted (by Presenter)
Description: An earthrise as seen from the surface of the moon.", "Presenter> The white text would go...", "Marker (by Presenter)
Description> Draws a red box..., and "Presenter> in this area." Notice that descriptions are appearing here. The lower-middle is the message composition area for this user and is blank. The upper-right is the whiteboard. So far there is an image of "earthrise" and a red hand-drawn rectangle on the "canvas". The whiteboard tools are "select box", "text tool", "marker", "eraser", "insert image", "line tool", "rectangle tool", and an "ellipse tool". In the lower-right is an area for describing a drawing action - in this case the "Presenter' use of the Marker". Notice that any participant can describe the events on the whiteboard even as the dialog continues. (Source: mockup by AUWG).
