I submitted a "metadata element for header" feature request
(http://sourceforge.net/tracker/index.php?func=detail&aid=958388&group_id=106328&atid=644065). It was declined through fears that such "viral" material would adversely affect the integrity of TEI.
Perhaps one could instead point to an RDF description of the
<topic id="myThing" ref="http://some.place/myThing.rdf"/>
