Jonathan,

The HTML specs (W3C and WHATWG) define a new Media Type registration for application/xhtml+xml, so there is going to be a new registration anyway, if not a new RFC. XHTML5 documents do not need to have an xmlns attribute pointing to the XHTML namespace -- that is defaulted -- though the draft registration [1] does mention that namespace and if you know where to look, the HTML5 spec does say that elements are in that namespace [2].

It may be that the existing namespace document is the best place for a registry (I can't see any reason to maintain two?) and just needs to be updated, or that it should point to a separate registry perhaps maintained in a more flexible method such as using a wiki. I think this is something we need to discuss.
