Erk, yes, good point. We should still note somewhere that WF2 documents 
*can't* be 'strictly conforming', according to the definitions in the 
XHTML1.0/1.1 specs. 

How about:
These XML documents may contain a DOCTYPE if desired, but this is not 
required. Note that these XML documents cannot be considered 'strictly 
conforming XHTML documents' as defined by the XHTML specification [XHTML1], 
as they contain content not defined by the XHTML specification.. 

or something similar. 

[Is there any reason this isn't on-list?]
