Sorry for being one day late (..but I had to honor presidents here and
take a day off.. ;)
The document was clear and I spotted no issues (bearing in mind my
limited HTTP proficiency). I did also check the ext-value ABNF with a
tool that it is correct (which it was).
The IDnits complains about non-ascii characters (pound, euro, etc). I
am not sure whether that will turn out to an "editorial" issue in the
final RFC text.
