On a first pass I like it very much.

1) The abstract syntax is intuitive and easy to read. It should be readily
possible to generate the full XML from this.

2) Is it true that the main difference between "Lite" and full "OWL" is that
the full version allows nested subClassOf definitions? If so, does this
justify a different name for the language? i.e. use of named and anonymous
types is not something difficult to grasp for the, e.g. XML developer who
has written a few DTDs or schemata.

3) Can we call "slots", "properties" which is slightly less idiomatic -- and
better understood by people not as familiar with the "frame" terminology.

All in all an excellent first pass.
