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.
