I don't think you're understanding our concern.

Yes, if the content author wishes to set the Accept-Language header, overriding the settings in the user's user agent (which is what you propose) in order to get the behavior you describe (which is a valid use case), then we need to provide a mechanism for them to use to do so.

However: 'hreflang' already exists in various markup languages related to XHTML2 and exists as an assertion about a particular resource based on that resource being static. XHTML2 proposes to change the meaning of that attribute from an assertion to override the user agent's local settings when requesting the resource. Therefore we feel strongly that you should name the attribute differently, more in line with what it does, so that there is no confusion about what the attribute does and what effect it should have on user agents. Otherwise existing generated content that is forward migrated will likely get unusual results based on (wrongly) mapping an assertion to an active attribute. And user agent authors may not implement the behavior correctly (either for XHTML2 or by wrongly changing the behavior for older markup).

Hope that helps.

BTW, Richard Ishida did note in our teleconference that you are proceeding to Last Call shortly. We are holding our other responses on your responses until we see the changes, per your request.

Best Regards,

Addison

Internationalization is not a feature.
It is an architecture.
