[XHTML 2] Section 3.1.1

Dear Working Group,

3.1.1 says that a strictly conforming XHTML 1.0 document ... MUST meet all 
the following criteria, then contains a list containing "There SHOULD be .."

This pattern is unclear, please change the introduction to 3.1.1 to remove 
the MUST constraint, or ensure that all the entries are a MUST.

An introduction saying:

"A strictly conforming XHTML 2.0 document is a document that requires only 
the facilities described as mandatory in this specification. Such a document 
should meet all the following criteria:"

Will remove any confusion.

Regards,

Jim Ley.
