[ODF metadata] Embedding IP/license information possible?

Hello

Chapters 2.x in the OpenDocument Metadata Use Cases and Requirements
Document at
http://www.oasis-open.org/committees/download.php/20492/UCR.odt
describe several use cases for metadata in ODF. One important one is
missing, I think:

The possibility to include IP/license information into a document.
Use case: A user wants to license his own document and add license
information somewhere as meta information (e.g., using CreativeCommons
licenses), is that possible?

Quote from a discussion in OO.org's bug-tracker: "Creative Commons is an
important way of adding IP licensing information to a document's
metadata. Of course, it should be integral to an overall IP metadata
format for OOo documents. A copyright notice, licensing information, and
digital signatures are critical."
