           Summary: New regex function to match and return a list of
                    captured strings

I am working on a project using XSLT 2.0, XQuery 1.0 and XPath 2.0. The project
involves some heavy use of regex and I really miss a feature. I would like to
be able to do match betweem a regex and a string and get back a list of
captured strings. 
For example I should be able to do a regex-match('2006 Location',
'(\d{4})\s+(.*)') and I would get back a list of matches ('2006', 'Location').
The closest existent matching function is replace, but it gives some problems
when it doesn't match the string. Instead of returning an empty string I get
the original string which forces me to do an extra check.
