xmlagg documentation

I just noticed that the xmlagg function is not documented. (Here is a random
piece of documentation for those who are not familiar with what it does:
http://docs.openlinksw.com/virtuoso/fn_XMLAGG.html) I'm wondering whether we
should put this with the aggregate functions or the XML functions, or both,
in some way. Any ideas?

It doesn't seem to fit with the other aggregate functions, so I think
I'd vote for documenting it with the XML functions.
