Hello, Mark, Shane, all.

In the process of making it easier for authors of XHTML to check their  
work, we've been looking at one specific type of document: XHTML  
documents not sporting a Doctype Declaration, but declaring the proper  
xhtml ns at their root element.

Something like:

Since the specifications for XHTML all require the presence of a  
doctype declaration for the document to be "strictly conforming" XHTML  
(1.0, 1.1, etc) such a document can not be "strictly conforming". Fair  
enough. But tools could still check it.

One idea that we had, was to build a DTD (and maybe an rng schema and  
xml schema too, why not) describing a "snapshot" of the aggregation of  
most known modules for XHTML.

Such a DTD could be interesting in itself. At this point in time, I am  
not aware of a DTD-friendly way of checking an XHTML document that  
uses both the features of ARIA and RDFa, for example.

Also, in the context of checking a document with the xhtml ns but no  
doctype, it would allow a tool to tell for sure if the document strays  
or not from the "xhtml realm".

Do you think:
*  it is a good idea?
*  you could provide some help in building such a snapshot DTD?
*  there would be a way to build this DTD in a way that allows easy  
addition of new modules?
   (my knowledge of modular xhtml is limited, so this may be a stupid  

Any help or feedback from the the X(HT)ML/SGML experts on this list  
would also be much welcome.

Thank you,
