shouldn't contraint's values be inlined?

[Koper, Dies]

Frederic asked me about resource metadata:

Is the XML serialization of attribute constraints correct ?
      <constraint>
        <value>UZXC0GRT-ZG8ZJCJ07</value>
      </constraint>
Should it just be <constraint>UZXC0GRT-ZG8ZJCJ07</constraint>  ?

He also pointed me to http://mantis.dmtf.org/mantis/view.php?id=1971.
Is this what the proposal envisioned?
mantis1971_v2.odt has "value constraints" in italics - not sure what to
make of that.
