I don't think so as it would violate one of the more important design principles the HTML WG has, namely that of DOM consistency. It also seems somewhat like a layering violation to care about xmlns attributes rather than namespace/prefix mappings. I wonder why that has not come up as an issue with RDFa in XHTML. >> I don't see how that >> can work without more text because xmlns and xmlns:<prefix> as generated >> from a text/html byte stream do not carry the namespace semantics xmlns >> and xmlns:<prefix> from a text/xml bytes stream do.

Non-normative user agent requirements would not address my concern, no. I'm not sure what requirement you are referring to here. > [1]http://rdfa.info/wiki/Html5-rdfa-wd-issues -- Anne van Kesteren http://annevankesteren.nl/
