To be done some time this week, if possible.

Several documents are labelled as being invalid for OWL Lite.  As I have an
OWL DL syntax checker, I can't process these tests.  However, the documents
are also probably not in OWL DL as well, and should be so labelled.

I'll try them again sometime soon.

This would cut down on the clutter.  The problem I had was determining
which classes and properties to look for.  Perhaps this is written down in
the manifest file itself and I can't see it for the clutter, but a document
making this easier would be helpful.
