Some portions, like the page header, abstract, and references section could 
be omitted from idnits checking for UTF-8.

For other sections which could have both normative and non-normative
content, I agree it would be good for idnits to generate warnings
(much as it does for certain classes of IP addresses whenever they're
used in a doc).

I disagree that permitting UTF-8 everywhere is "clean" :)
