[XHTML 2] Conforming documents and meta properties

Dear HTML Working Group,

3.1.1.1 states that a Conforming XHTML 2.0 document must conform to the 
specifications of a DTD (I realise it's not yet written) however I wish to 
use my own private namespaces in the in the meta properties i.e.

<meta about=http://www.example.com/ 
xmlns:jim="http://jibbering.com/chickens" 
property="jim:created">2004-03-20</meta>

However I doubt there's any chance of the DTD ever being authored with an 
xmlns:jim attribute in it (and if there is, not for any of the other 
infinite namespaces I could use.)

Please either remove the requirement for DTD conformance, or remove the 
requirement that we reference the DTD in Appendix H (so we can author our 
own) or remove the problem of using QNames in attribute context.

Regards,

Jim Ley
