Hi Stephanie,

The GLI doesn't support this ability, sorry. The values in the value
tree at the bottom right of the Enrich Pane are read from the
metadata.xml files in the collection, every time the collection is
loaded. If you know Java (or someone who does) it probably wouldn't be
too hard to hack this into the GLI. It doesn't really fit the GLI's
metadata model though so it might not be pretty.

Thanks for letting us know about the XML validation problems, we'll have
to investigate those.

Regards,

Michael
