It doesn't really work.  Not only is there the problem you mention, but 
there's also the problem of expanding and merging EntiryRefs.

Rich says all he needs to solve is the CDATA-as-sole-child problem.  I say 
that this problem is so non-general that I'd hate to see specialized code to 
solve it withough at least some discussion of how to solve the general problem.

In other words, I'd not like to see code checked in to 4XPath that blindly 
checks for CDATASection nodes wherever it's looking for TEXT nodes.
