This document lists the techniques used by Amaya (or in development
for Amaya) to satisfy the Authoring Tool Accessibility Guidelines 1.0
[ATAG10]. It is intended to assist developers seeking to implement
the Authoring Tool Accessibility Guidelines 1.0.
Note: The techniques in this document are merely
suggestions; they are not required for conformance to the Authoring
Tool Accessibility Guidelines 1.0. These techniques are not
necessarily the only way of satisfying the checkpoint, nor are they
necessarily a definitive set of requirements for satisfying a
This document has the same structure as the Authoring Tool
Guidelines 1.0 [ATAG10]. Each guideline and checkpoint from that
document is listed, in the same order, with an explanation of Amaya's
techniques for implementing them, or techniques that the development
team plans to implement.
Guideline 1. Support accessible authoring
- 1.1 Ensure that the author can produce accessible content in the markup language(s) supported by the tool. [Priority 1]
- Amaya implements all of the accessibility
features of HTML. The CSS cascade order, an accessibility feature of
CSS2, has not yet been completely implemented in Amaya.
- 1.2 Ensure that the tool preserves all accessibility information during authoring, transformations, and conversions. [Priority 1]
- The predefined transformations shipped with
Amaya preserve all element content. The transformation language
allows the preservation of attribute values, but this is not done by
all the supplied transformations.
- 1.3 Ensure that when the tool automatically generates markup it conforms to the W3C's Web Content Accessibility Guidelines 1.0 [WCAG10]. [Relative Priority]
- Amaya generates markup that conforms to
level-A, and allows the author to generate markup that is triple-A
through the user interface.
- 1.4 Ensure that templates provided by the tool conform to the Web Content Accessibility Guidelines 1.0 [WCAG10]. [Relative Priority]
- Amaya has templates, which have not yet been
checked for conformance to WCAG
Guideline 2. Generate standard markup.
- 2.1 Use the latest versions of W3C Recommendations when they are available and appropriate for a task. [Priority 2]
- Amaya supports HTML 4 [HTML4], XHTML 1.0
[XHTML10], and most of CSS1 [CSS1]. It provides partial support
for MathML [MATHML] and some experimental support for Scalable
Vector Graphics [SVG].
- 2.2 Ensure that the tool automatically generates valid markup. [Priority 1]
- Amaya implements each language according to
the published specifications.
- 2.3 If markup produced by the tool does not conform to W3C specifications, inform the author. [Priority 3]
- If Amaya imports or generates markup that
does not conform to W3C specifications it is highlighted in the
structure view. This occurs when Amaya tries to repair invalid
markup and cannot successfully do so.
Guideline 3. Support the creation of accessible
- 3.1 Prompt the author to provide equivalent alternative information (e.g., captions, auditory descriptions, and collated text transcripts for video). [Relative Priority]
- Amaya prompts the author to provide
equivalent text for
CAPTION for the
- 3.2 Help the author create structured content and separate information from its presentation. [Relative Priority]
- In future releases Amaya is expected to
prompt the author for
form controls. The
user interface of Amaya was developed to guide authors to produce
structured documents. Style in Amaya is created as a
- 3.3 Ensure that prepackaged content conforms to the Web Content Accessibility Guidelines 1.0 [WCAG10]. [Relative Priority]
- Amaya does not provide any clip art or other
- 3.4 Do not automatically generate equivalent alternatives. Do not reuse previously authored alternatives without author confirmation, except when the function is known with certainty. [Priority 1]
- 3.5 Provide functionality for managing, editing, and reusing alternative equivalents for multimedia objects. [Priority 3]
Guideline 4. Provide ways of checking and
correcting inaccessible content.
- 4.1 Check for and inform the author of accessibility problems. [Relative Priority]
- Amaya currently checks for validity, but the
only warning of invalid markup appears in the structure view. The
Amaya developers are investigating automating an accessibility check
and author notification. Where Amaya detects an error, it identifies
and highlights the incorrect code in the structure view, allowing
the author to delete it.
- 4.2 Assist authors in correcting accessibility problems. [Relative Priority]
- 4.3 Allow the author to preserve markup not recognized by the tool. [Priority 2]
- 4.4 Provide the author with a summary of the document's accessibility status. [Priority 3]
- 4.5 Allow the author to transform presentation markup that is misused to convey structure into structural markup, and to transform presentation markup used for style into style sheets. [Priority 3]
- Amaya provides a language for specifying
structure transformations, and a large number of predefined
transformations are included.
Guideline 5. Integrate accessibility
solutions into the overall "look and feel".
- 5.1 Ensure that functionality related to accessible authoring practices is naturally integrated into the overall look and feel of the tool. [Priority 2]
- In Amaya some accessibility features are part
of relevant dialogs. Others, such as longdesc and title attributes
must be separately generated by the author. The development team
will integrate these into the relevant dialogues in future
- 5.2 Ensure that accessible authoring practices supporting Web Content Accessibility Guidelines 1.0 [WCAG10] Priority 1 checkpoints are among the most obvious and easily initiated by the author. [Priority 2]
- Amaya's user interface guides the author to
produce structured content, with presentation elements separated
into style sheets. Providing an equivalent alternative is mandatory
at the time of inserting some elements.
Guideline 6. Promote accessibility in help and
- 6.1 Document all features that promote the production of accessible content. [Priority 1]
- Amaya help pages for images and image maps
[AMAYA-HELP-IMG] include providing text alternatives as part of
the process. There is a help page on configuring Amaya, that
documents how to change the default keyboard bindings.
- 6.2 Ensure that creating accessible content is a naturally integrated part of the documentation, including examples. [Priority 2]
- Accessible authoring features are added to
the documentation as they are incorporated into Amaya, as part of
the normal documentation of the relevant feature.
- 6.3 In a dedicated section, document all features of the tool that promote the production of accessible content. [Priority 3]
- Amaya documentation has a basic accessibility
section, which is an option in Amaya's help menu.
Guideline 7. Ensure that the authoring tool is
accessible to authors with disabilities.
- 7.1 Use all applicable operating system and accessibility standards and conventions (Priority 1 for standards and conventions that are essential to accessibility; Priority 2 for those that are important to accessibility; Priority 3 for those that are beneficial to accessibility).
- Amaya is currently available for two
platforms: Unix and Windows. There is some work required on both
platforms to bring it into line with conventions, in particular to
provide conformance with the User Agent Guidelines [UAAG10], and
to implement Microsoft Active Accessibility [MSAA] in the Windows
version. It is being re-written to take advantage of the improved
accessibility support possible in Gnome (it currently uses Motif) in
the Unix version. The Documentation is all available online as HTML
and has been reviewed to ensure it conforms to WCAG 1.0 [WCAG10].
- 7.2 Allow the author to change the presentation within editing views without affecting the document markup. [Priority 1]
- Amaya allows the author to create local style
sheets, and to enable or disable each style sheet that is linked to
- 7.3 Allow the author to edit all properties of each element and object in an accessible fashion. [Priority 1]
- Amaya allows each attribute to be edited
through the menu or through the structure view. Element types can be
assigned through the menu system.
- 7.4 Ensure that the editing view allows navigation via the structure of the document in an accessible fashion. [Priority 1]
- Amaya provides a structure view, that can be
navigated element by element, a Table of Contents view, that allows
navigation via the headings, and a links view, that allows
sequential navigation via the links in the document. It also
provides configurable keyboard navigation of the HTML structure -
parent, child, next and previous sibling elements.
- 7.5 Enable editing of the structure of the document in an accessible fashion. [Priority 2]
- Amaya allows the author to select elements (including containers) and cut,
copy and paste them with their attributes and properties in any of
the formatted, structure and alternate views.
- 7.6 Allow the author to search within editing views. [Priority 2]
- Amaya provides a search function. Because all
editing views are synchronized, any search text found will be
selected in each of the available views.
