ROSO — Definition of Commons to be included in the (non-normative) XMI.

Definitions of Commons are not included in the (non-normative) XMI.
Should a UML version of Commons be needed (not necessarily a bad idea), that should be achieved through an update to the Commons spec—which could be through the RTF or, at a pinch, by detailing the changes in this new submission in the Changes to Other Specifications section. In no circumstances should the Commons classes (or indeed lcc:Location or owl:Thing) be included in this XMI but referenced via hrefs.
