Thanks for pointing this out. You are correct that this is undesirable, and unintentional. ICWGIT> We think this should actually say: ICWGIT> "The possible values for the lang attribute MUST conform to BCP 47." Yes, that would be the more usual way to say this and consistent with what other W3C specifications do. I propose that we accept this comment as-is. This change adds to the list of languages, but does not have any impact on existing deployed content. Content with lang="en" continues to be fine, but now you can say lang="en-US" for example. I'm fairly sure that this was the original intent anyway. ICWGIT> An there should be an entry for BCP 47 in the References section. Yes, that would be a natural consequence of your proposed change. (For those unfamiliar with IETF terminology, BCP is a Best Current Practice document and intended to be a stable reference. At any given time it points to one or more IETF RFCs, and the ones it points to may be updated over time as one RFC supercedes another.

Yes, this is better wording, and more stable as it does not need to be updated in the future if RFC 4647 is updated. Yet in terms of implementations, it means the same thing so there is no change to code there. -- Chris Lilley Technical Director, Interaction Domain W3C Graphics Activity Lead, Fonts Activity Lead Co-Chair, W3C Hypertext CG Member, CSS, WebFonts, SVG Working Groups
