[Chris Lovett] This was bogus - and will be removed.

[Chris Lovett] Sorry about that. The wonders of Visual J++ I guess.

[Chris Lovett] Yes, we've talked about this in the DOM group.

[Chris Lovett] Careful how much you rail against this schema format. This
is just plain XML you know. If you are having a hard time navigating plain
XML then perhaps the Object Model needs richer navigational methods...

[Chris Lovett] You'll get a <BAR> element in the object model if you drop
the CDATA section. So you're entity would be: <!ENTITY foo '<bar>blah blah
blah</bar>'>
