My version 0.1 recommendations (ccts-comments-ubl-0-1.doc) attempt to integrate my properties proposal with Arofan's RT/CCT one. At least the proposed _metamodel_ is integrated (I left a placeholder for his prose -- to be added). Arofan has agreed to look at that document and comment on the metamodel (does it reflect his proposal accurately). Have you got the LCSC comments in a form that I can see, Tim? If they aren't too onerous I could take a crack at integrating them in version 0.2.
