Section 4.3 reference to character model

Section 4.3 states:

The [Character Model] 
<http://www.w3.org/TR/2003/WD-xinclude-20031110/#CharMod> discusses 
normalization of included text.


I'm afraid that's at most suggestive. This needs to be spelled out 
further. For example, at one extreme do you mean to say that when 
parse="text", then the text must be include normalized (which implies 
Unicode NFC) as defined in section 4.2.2 of the Character Model draft? 
Or perhaps the other extreme, of simply non-normatively referencing this 
spec in order to make implementers aware of the issues of text 
normalization? Or something in between or completely different? The 
Character Model reference in the bibliography is in the non-normative 
section.

I think it's very important to tighten up this sentence, and make it 
clear whether this is a mandatory requirement or a non-normative reference.
