Here's the patch to add the 'xml_is_well_formed' function. Paraphrasing 
the SGML the syntax is:

|xml_is_well_formed|(/text/)

The function |xml_is_well_formed| evaluates whether the /text/ is well 
formed XML content, returning a boolean. I've done some tests (included 
in the patch) with tables containing a mixture of well formed documents 
and content and the function is happily returning the expected result. 
Combining with IS (NOT) DOCUMENT is working nicely for pulling out 
content or documents from a table of text.

Unless I missed something in the original correspondence, I think this 
patch will solve the issue.
