The only problem is: where to put such statement? Putting it into

http://www.w3.org/1999/xhtml/vocab

is not that easy, it would require working group agreement that 'owns'
this document...

(hence my copy of this mail to Ralph and Steven, although Steven is on
vacations right now...)

b.t.w., rel="license" already maps to xh:licence in RDFa. Ie, it is the
'default' licence property for RDFa. One more reason for this...
