Re: Conformance notes.

http://www.w3.org/TR/2006/WD-WCAG20-20060427/conformance.html#conformance-claims

The Note suggests that the default version of the content displayed (i.e. Web unit that is returned when no negotiation is conducted) is the one that must comply. This would mean that myself for example, as a fully able user with no content negotiation enabled, would be forced to view the most accessible version of a content unit, despite, perhaps, a less accessible, more interactive, "flashy" version being more appropropriate for my needs.

Proposed Change:

I think the second statement (in parentheses) "...one of the negotiated forms must comply" makes more sense as the default here, with perhaps the added note that "...the most accessible version is easily accessed should the primary version not be accessible". A common example is the Flash splash page that includes a link to an accessible HTML version of the same content. In the initial statement it suggested that as a developer I would have to default to the HTML version of the page, with a link to the Flash version instead. Developers and their clients will not agree to this, but they will agree to a link that leads to a more accessible version..

WG Notes: [TEAMB] submitted by Team A 5/23/06 Discussed 25 May 2006: Resolution: 534 sent back for exact wording That is now Done. Ready for re-surveying. -- Discussed on the 22 June 2006 teleconference Resolution: Accept proposal for issue LC 534 as edited. http://www.w3.org/WAI/GL/2006/06/22-wai-wcag-minutes.html DONE Clean up language so that it is clear that what is already written allows for the case he describes. Specifically change: "Note: If multiple representations can be retrieved from a URI through content negotiation, then the conformance claim would be for the Web unit that is returned when no negotiation is conducted (unless the server returns an error for that condition, in which case one of the negotiated forms must comply) (Refer to success criterion 4.2.1 .) " TO "Note: If multiple representations can be retrieved from a URI through content negotiation, then the conformance claim would be for the Web unit that is returned when no negotiation is conducted (unless the server returns an error for that condition, in which case one of the negotiated forms must comply). This version does not need to be fully accessible itself, but fully accessible content must be available from that web unit in a manner that fully conforms to WCAG 2.0 at level A.

This version does not need to conform itself, but an alternate version must be available from that Web page in a manner that fully conforms to WCAG 2.0 at the level claimed. DONE refer to proposed revisions to CC4, Understanding documents and techniques at <http://tinyurl.com/34wxyx> Internal WD updated 21 March 2007 Response: http://lists.w3.org/Archives/Public/public-comments-wcag20/2007Jun/0068.html

Resolution: We have removed discussion of content negotiation and moved requirements related to alternate versions to the Conformance section of the Guidelines. The revised conformance criteriaon now reads: Alternate Versions: If the Web page does not meet all of the success criteria for a specified level, then a mechanism to obtain an alternate version that meets all of the success criteria can be derived from the nonconforming content or its URI, and that mechanism meets all success criteria for the specified level of conformance. The alternate version does not need to be matched page for page with the original (e.g. the alternative to a page may consist of multiple pages). If multiple language versions are available, then conforming versions are required for each language offered.
