ODF 1.2 comment: metadata: OWL

The OWL material does not gel. I am not an expert in OWL, but I note that
the OWL schema references resources that do not exist.

For example, the following fragments are referenced but do not apparently
exist:

http://docs.oasis-open.org/ns/office/1.2/meta/pkg#File
http://docs.oasis-open.org/ns/office/1.2/meta/odf#Element
http://docs.oasis-open.org/ns/office/1.2/meta/pkg#Element

These appear as subclasses in the owl file. From the OWL specification, it
seems that these are supposed to reference some class definition*,
following RDFS. I was not aware that an HTML file with no corresponding
fragments ids satisfies RDFS.

(I suspect that part of the OWL schemas has gone missing: these would have
been in the above files pkg and odf at some stage.)

SUGGESTION: Correct the OWL schemas. Validate them in some appropriate
tool with no loose ends.

Cheers
Rick Jelliffe
