Looking at your pattern, by including \w*|\W* (i.e. anything that is a
word character or anything that isn't a word character), then I think
your pattern will match anything, so it's probably not providing you
any validation beyond xs:string.

My test of the pattern seemed to say the pattern was correct.  If
trying to match <![CDATA[... is giving you grief, how about trying to
match something like .![CDATA[... and then checking that the first
character is a < later?  (A bit of a hack, but might ease your
suffering:-)

HTH,

Pete.

P.S. As you mentioned, there are small differences between the likes
of Perl regular expressions and xml schema regular expressions, but
they don't come into play with the pattern you have.  You have escaped
things like < and ! more than necessary, but this shouldn't be a
problem.
