HTML Working Group Charter

This is a previous DRAFT of the charter for review. It has been updated and modified. The HTML WG is working under a new charter.

The mission of the HTML Working Group, part of the HTML Activity, is to continue the evolution of HTML (including classic HTML and XML syntaxes).

This group will maintain and produce incremental revisions to the HTML specification, which includes the series of specifications previously published as XHTML version 1. Both XML and 'classic HTML' syntaxes will be produced.

The Group will define conformance and parsing requirements for 'classic HTML', taking into account legacy implementations; the Group will not assume that an SGML parser is used for 'classic HTML'.

The Group will monitor implementation of and conformance to the HTML specification, construct test suites, and from them produce interoperability reports.

The Group may hold Workshops, Interoperability Meetings, and other events as required to fulfill its mission.

Success Criteria

The HTML Working Group's work will be considered a success if there are two independent complete and interoperable implementations of its deliverable that are widely used (more than 10% of the Web browser market each according to at least two widely recognized metric reporting organizations).


New publications and Milestones

There is a single specification deliverable for the HTML Working Group, the HTML specification, with the following items in scope:

The following features are expected to be obtained by integrating deliverables of the Web APIs Working Group. They are listed here so that they may be developed in the case where the Web APIs Working Group is not able to produce the specifications.

Note that some of the features mentioned above may be obtained by integrating deliverables of the Web APIs Working Group.

Other Deliverables

The Group will create a comprehensive test suite for the HTML specification.

The Group will ensure that validation tools are available, possibly from third parties, for the HTML specification.

The Group will monitor, track, and encourage implementation of HTML, both during Candidate Recommendation and afterwards, to encourage adoption.


Note: The group will document significant changes from this initial schedule on the group home page.

Dependencies and Liaison

The following is a list of known dependencies and liaisons with other W3C groups at the time this charter was written. Liaison with other W3C groups can take advantage of a broad range of mechanisms such as cross membership, reviews of drafts produced by other groups, joint meetings etc., and whenever appropriate, the HTML Working Group will also coordinate with groups not listed here.


Web APIs Working Group
HTML will integrate APIs developed by this Working Group


Compound Document Formats Working Group
The HTML Working Group cooperates with this group to ensure that HTML can be readily combined with other W3C specifications
Cascading Style Sheets (CSS) Working Group and Extensible Stylesheet Language (XSL) Working Group
The work of the HTML Working Group will be coordinated with these groups on presentation issues.
Forms Working Group
The HTML Working Group will work closely with this group, via a joint task force, to ensure a smooth transition to next generation Web forms.
Hypertext Coordination Group
The Hypertext Coordination Group is the primary place for the HTML Working Group for coordination with other Working Groups within the W3C. The Chair will participate in the regular Hypertext Coordination Group meetings and ensure that reviews between Working Groups are planned and carried out so as to meet requirements for deliverables and deadlines.
Internationalization Working Group
The HTML Working Group will cooperate with this group to ensure HTML provides effective support for internationalization.
Technical Architecture Group (TAG)
The HTML WG will liaise with the TAG, in particular regarding issue TagSoupIntegration-54.
Web Accessibility Initiative (WAI)
The HTML Working Group will cooperate with the Web Accessibility Initiative to ensure that the deliverables will satisfy accessibility requirements. Coordination with WAI will be primarily conducted through the Protocol and Formats Working Group, but direct coordination with other WAI groups, such as Web Content Accessibility Guidelines Working Group and User Agent Accessibility Guidelines Working Group, will also be done when appropriate.

Furthermore, HTML Working Group expects to follow these W3C Recommendations:

Relationship to External Groups

There is no formal relationships to groups outside the W3C.

However, the Working Group will attempt to liaise with external groups, such as the WHAT WG, and with the content developer community.


To be successful, the HTML Working Group is expected to have active participation for its duration. If fewer than three implementors (i.e., browser vendors) are participating in the Working Group, its charter should be re-examined by the W3C.

The Chair, Team Contact and specification Editors are expected to contribute at least two days per week towards the Working Group. There is no minimum requirement for other Participants.

W3C Members may join the Working Group using the regular W3C process.

Participants are reminded of the Good Standing requirements of the W3C Process.

The HTML Working Group also welcomes participation from non-Members. This may take the form of questions and comments on the mailing list or IRC channel, for which there is no formal requirement, or technical submissions for consideration, for which the participant must agree to Royalty-Free licensing under the W3C Patent Policy.


This group primarily conducts its technical work on a Public mailing list public-html, to be created following charter approval (archive), It is referred to in the rest of this document as the Working Group mailing list.

A Member-only mailing list, member-html, to be created following charter approval (archive) is available for administrative purposes only.

Information about the group (deliverables, participants, face-to-face meetings, teleconferences, etc.) will be available from the HTML Working Group home page.

Decision Policy

As explained in the Process Document (section 3.3), this group will seek to make decisions when there is consensus. When the Chair puts a question and observes dissent, after due consideration of different opinions, the Chair should record a decision (possibly after a formal vote) and any objections, and move on.

This charter is written in accordance with Section 3.4, Votes of the W3C Process Document and includes no voting procedures beyond what the Process Document requires.

Patent Policy

This Working Group operates under the W3C Patent Policy (5 February 2004 Version). To promote the widest adoption of Web standards, W3C seeks to issue Recommendations that can be implemented, according to this policy, on a Royalty-Free basis.

For more information about disclosure obligations for this group, please see the W3C Patent Policy Implementation.

About this Charter

This charter for the HTML Working Group has been created according to section 6.2 of the Process Document. In the event of a conflict between this document or the provisions of any charter and the W3C Process, the W3C Process shall take precedence.
