Certainly, you can put XML in a TEXT field. Of course, without
XML-oriented retrieving tools, it is not very useful. At, least, with
xml2 (see beyond), you can insert XML and check if it is well-formed.

Why not Xpath? It is supported in PostgreSQL (see
http://developer.postgresql.org/cvsweb.cgi/pgsql/contrib/xml2/README.xml2)
but I do not know about the performance (I don't know if there is
XML-oriented indexation).
