Michael, I think that the best place to ask this question is in fact the WCAG working group, who wrote the checkpoint in question - w3c-wai-gl@w3.org is their mailing list and archives are at http://lists.w3.org/Archives/Public/w3c-wai-gl although I am pretty sure that this question hasn't been asked there yet. For what it is worth my personal opinion would be that in regards to specifying languages what you propose below is sufficient, but minimal. To do better it is possible to have information in the content as well as having hreflang attributes - not all tools will interpret the attribute. It is also possible to have rel="alternate" in A or LINK elements that point to alternative language versions of the same document - this is mostly useful for the link element I think. Server-based content negotiation is also an important technique - if you have much multilingual content I strongly recommend it. And if there are other alternatives available I recommend it even more strongly - perhaps through something like a CC/PP proxy (for more details see the CC/PP work at http://www.w3.org/Mobile/CCPP but the basic idea is that it provides a framework for describing different versions of content available and matching them with different user profiles). cheers Charles McCathieNevile On Mon, 17 Jun 2002, Virant, Michael W wrote: Checkpoint 11.3 - - Provide information so that users may receive documents according to their preferences. http://www.w3.org/WAI/wcag-curric/sam89-0.htm states: "If it is not possible to use content negotiation at a server level, in HTML use 'hreflang' with the <A> or <LINK> elements to identify the language of the target documents." To meet checkpoint 11.3 for a site without content negotiation, is it sufficient to use 'hreflang' in all <A> links to content? Further - if Checkpoint 4.3 is met, will 11.3 also be met if 'hreflang' is only used in <A> links to content in languages other than that for the referring document?
