True for most folk.  XML made me get my hands dirty with
I18N stuff, and that one took a while for me to grok.  I don't
think it'll be intuitive to most folk, who've rarely had to look
at such I18N issues.

Yes, I was thinking of doing that.  After I imbibe the other thread
a bit more deeply, to make sure I pick up any other details.  That
should make it into the SAX2 r2 ContentHandler docs, and maybe
also LexicalHandler.comment() if I get ambitious.
