It was discussed during the SWIG f2f meeting at Mandelieu. We are researching how to make compatible the basic foundations of qualities and quales (that are the inpiration for MUO) and the semantics of DL functional properties. Actually, we were awaiting to come up with a satisfactory solution for this issue before preparing the member submission to W3C. We would be pleased to futher discuss this issue, probably in a separate thread.
