Are you referring to fantasai and me? I am not doing anything with  
DTDs. AFAIK, fantasai isn't working on DTDs, either, currently.

There have been forward-looking statements about DTD or XSD versions  
of the schema generated from the RELAX NG master. Considering the  
level of RELAX NG-specific features used in the schema, I'd expect  
Trang-generated DTDs and XSDs to be rather imprecise. Moreover,  
personally, I don't like the idea of generating DTDs, because it  
would encourage people to use doctypes and would give them a false  
sense of security (after validation against an imprecise DTD).

More precisely, (X)HTML5 will not have a normative schema of any  
kind. The English prose is normative. Furthermore, letting schemas  
affect the design of the language doesn't go down well with Hixie.  
(Yes, I tried after all. :-)

That said, considering my sunk cost in contributing to the RELAX NG  
schema, I'd appreciate it if the language did not gain features that  
are too crazy for RELAX NG + Schematron. :-)

Need to know how to write a normative DTD???
