comment on XML ID appendix E

I have a comment on

http://www.w3.org/TR/2005/REC-xml-id-20050909/#id-avn



Specifically the text:

[[

Note:

For interoperability, document producers <a title="Must, May, etc." 
href="#dt-must">should</a>
]]

I suggest

[[
Note (normative):

For interoperability, document producers <a title="Must, May, etc." 
href="#dt-must">should</a>
]]

or

[[

Note:

For interoperability, document producers are advised to
]]


would be better.

(i.e. in my view, it is good policy to only use the RFC 2119 keywords 
with their full force in normative text. In informative text, it is best 
to avoid the keywords, lest their be confusion as to the intended force 
of the statement).

I have a mild preference for the former change - I think this 'should' 
does deserve RFC 2119 force.
