The XHTML2 abstract says:

# XHTML 2 is a general-purpose markup language designed for representing 
# documents for a wide range of purposes across the World Wide Web. To 
# this end it does not attempt to be all things to all people, supplying 
# every possible markup idiom, but to supply a generally useful set of 
# elements.

This is also repeated in the introduction.

However, the term "documents" is never defined, and the phrae "a wide 
range of purposes" seems very vague in terms of defining the scope of the 
specification.

For example, are documents such as interactive applications like those 
hosted at http://maps.google.com/ , http://www.voidwars.com/ , 
http://waronline.net/ , http://fslactivities.sd61.bc.ca/editez/ , and the 
like, in scope or out of scope of this specification?

Please clarify the scope of the XHTML2 specification in the introduction.
This will also improve the specification's conformance to the QA 
Framework: Specification Guidelines document, section 2.2.1.

Cheers,
