Conformance Proposal

From: Jeanne Spellman <jeanne@w3.org>

Message-ID: <4B86C9D3.2090400@w3.org>

Conformance
This section is normative.
Conformance means that the user agent satisfies the success criteria 
defined in the guidelines section. This conformance section describes 
conformance and lists the conformance requirements.
Conformance Requirements
In order for a Web page to conform to WCAG 2.0, all of the following 
conformance requirements must be satisfied:
1. Conformance Level: One of the following levels of conformance is met 
in full.
Level A: For Level A conformance (the minimum level of conformance), the 
user agent satisfies all the Level A Success Criteria.
Level AA: For Level AA conformance, the user agent satisfies all the 
Level A and Level AA Success Criteria.
Level AAA: For Level AAA conformance, the user agent satisfies all the 
Level A, Level AA and Level AAA Success Criteria.
Note 1: Although conformance can only be achieved at the stated levels, 
developers are encouraged to report (in their claim) any progress toward 
meeting success criteria from all levels beyond the achieved level of 
conformance.
Conformance Claims
If a conformance claim is made, then the conformance claim must meet the 
following conditions and include the following information (user agents 
can conform to UAAG 2.0 without making a claim):
Conditions on Conformance Claims
At least one version of the conformance claim must be published on the 
web as a document meeting level "A" of WCAG 2.0. A suggested metadata 
description for this document is "UAAG 2.0 Conformance Claim".
Whenever the claimed conformance level is published (e.g., product 
information web site), the URI for the on-line published version of the 
conformance claim must be included.
The existence of a conformance claim does not imply that the W3C has 
reviewed the claim or assured its validity.
Claimants may be anyone (e.g., user agent developers, journalists, other 
third parties).
Claimants are solely responsible for the accuracy of their claims 
(including claims that include products for which they are not 
responsible) and keeping claims up to date.
Claimants are encouraged to claim conformance to the most recent version 
of the User Agent Accessibility Guidelines Recommendation.
Required Components of an UAAG 2.0 Conformance Claim
1.Claimant name and affiliation.
2.Date of the claim.
3.Conformance level satisfied.
4.User agent information: The name of the user agent and sufficient 
additional information to specify the version (e.g., vendor name, 
version number (or version range), required patches or updates, human 
language of the user interface or documentation).
Note: If the user agent is a collection of software components (e.g., a 
browser and extentions or plugins), then information must be provided 
separately for each component, although the conformance claim will treat 
them as a whole. As stated above, the Claimant has sole responsibility 
for the conformance claim, not the developer of any of the software 
components.
5.Included Technologies: A list of the web content technologies 
(including version numbers) rendered by the user agent that the Claimant 
is including in the conformance claim. By including a web content 
technology, the Claimant is claiming that the user agent meets the 
requirements of UAAG 2.0 during the rendering of web content using that 
web content technology.
Note 1: Web content technologies may be a combination of constituent web 
content technologies. For example, an image technology (e.g., PNG) might 
be listed together with a markup technology (e.g., HTML) since web 
content in the markup technology is used make web content in the image 
technology accessible (e.g., a PNG graph is made accessible using an 
HTML table).
6.Excluded Technologies: A list of any web content technologies produced 
by the the user agent that the Claimant is excluding from the 
conformance claim. The user agent is not required to meet the 
requirements of UAAG 2.0 during the production of the web content 
technologies on this list.
7.Declarations: For each success criterion:
A declaration of whether or not the success criterion has been 
satisfied; or
A declaration that the success criterion is not applicable and a 
rationale for why not.
8.Platform(s): The platform(s) upon which the user agent was evaluated:
For user agent platform(s) (used to evaluate web-based user agent user 
interfaces): provide the name and version information of the user agent(s).
For platforms that are not user agents (used to evaluate non-web-based 
user agent user interfaces) provide: The name and version information of 
the platform(s) (e.g., operating system, etc.) and the the name and 
version of the platform accessibility architecture(s) employed.
Optional Components of an UAAG 2.0 Conformance Claim
1.A description of how the UAAG 2.0 success criteria were met where this 
may not be obvious.
"Progress Towards Conformance" Statement
Developers of user agents that do not yet conform fully to a particular 
UAAG 2.0 conformance level are encouraged to publish a statement on 
progress towards conformance. This statement would be the same as a 
conformance claim except that this statement would specify an UAAG 2.0 
conformance level that is being progressed towards, rather than one 
already satisfied, and report the progress on success criteria not yet 
met. The author of a "Progress Towards Conformance" Statement is solely 
responsible for the accuracy of their statement. Developers are 
encouraged to provide expected timelines for meeting outstanding success 
criteria within the Statement.
Disclaimer
Neither W3C, WAI, nor UAWG take any responsibility for any aspect or 
result of any UAAG 2.0 conformance claim that has not been published 
under the authority of the W3C, WAI, or UAWG.
