CLARIFICATION: normativity in XCF chapter.

[Lofton Henderson <lofton@rockynet.com>]

In the CD2 text [1], the DOM chapter (Ch.5) was missing the normal 
declaration, right after the chapter header, whether the chapter was 
normative or informative.  Therefore I added, "This section and its 
subsections are normative, unless otherwise indicated."

It seems to me that each of 5.1 and 5.2 is informative -- the do not 
contain any conformance requirements against which metafiles or 
implementations can be tested.  So to each of these I added, "This 
subsection is informative (non-normative)."

Okay?

Btw, if you want to comment further on this topic, please have a look first 
at the "Normativity" subsection  (A.5) of the Conformance Clause appendix 
[3], Appendix A.  Added for the CD2 text, A.5 is a beginning at further 
clarifying what is normative and informative, and how conformance 
requirements are expressed and recognized (it derives from work done in 
W3C's QAWG).
