[ACTION-14] features document and xhtml versions

In starting work on this document, it occurred to me that the document 
should not only provide identifiers for the "features" of xhtml that 
@implements might point at, but also provide a grounded mapping for 
values of @version.  In this way a follow-your-nose processor could 
determine what version of XHTML was in use in a document and how that 
version relates to others.  Maybe, anyway.  If nothing else, it would 
allow us to have an extensible registry for XHTML versions.  This would 
have an impact on the permitted values of @version, of course. We 
already reserve values starting with the characters 'xhtml', so perhaps 
that is enough.
