Jim, for those of us who were not at the meeting, can you provide some additional clarification on teh requirement spec for OWL. I guess the proposed requirements are to be interpreted as additional requirements on top of what daml+oil already provides. is this correct? And I guess I should also infer that what is not currently in daml+oil and is not listed below is not going to be in OWL. Is this is also a correct inference?
