Oh I'm sure there are plenty of ways to handle the RDF problem space in 
text/html, assuming we establish that as being a problem worth solving in 
HTML5. I haven't had a chance to look closely at the feedback on RDF yet, 
there are a number of topic areas, in particular the forms, video, and 
offline features, that have a higher priority and have to be dealt with 
first.

A lot of the data on namespace issues is collected here:

   http://wiki.whatwg.org/wiki/Namespace_confusion

The edict against DOM inconsistency is primarily borne of feedback from 
browser vendors.

In the WHATWG the editor (me, for HTML5) makes the decisions, which can 
then be overriden by the core membership (as defined at the bottom of the 
charter) if they disagree with it:

The WHATWG process is described in the FAQ:

   http://wiki.whatwg.org/wiki/FAQ#The_WHATWG_Process


Note however that I do not expect the namespace issue to materially affect 
the RDFa feedback; I'm sure there are many ways of addressing the problem 
space of RDF that do not involve having to use namespace prefixes.
