Re: [xml] bug in xmllint parsing of content model

Yes, it's all an ingenious plot designed to help decrease the ridicu-
lous commercialism associated with Valentine's Day (at least here in
the USA -- I don't know where you are) by keeping you busy so you
won't go out shopping.

Seriously, unless the other reporting party was S. Rahtz or L.
Burnard, I have nothing to do with it. (And even if it was, I didn't
realize they were reporting it, although perhaps I should have.)

And yes, I wrote the above rant just to align with my whine-about-
valentine's-day-packaging example described in previous mail.

Glad to hear it; hope so.

Errrr, um ... sorry. I feel a bit silly having trouble attaching a
simple text document to mail (using vm 7.07 under Emacs 21.2.1, in
case anyone has any suggestions). I'll try again:

<?xml version="1.0" encoding="UTF-8" ?>

            )
          )
