This was discussed in today's telecon (2008-07-23), but I'm uncertain my view was clearly expressed. On Wed, 2008-07-16 at 17:52 +0100, Boris Motik wrote: > 1.

Note 2: The value space is NOT discrete. Note 2 (discrete value space) is a divergence from XML Schema. I would prefer that the value space xsd:float and xsd:double be discrete subsets of owl:numberPlus. If others feel this makes the burden of implementation too high, I think a compromise is to not support float and double in class restrictions. > 2.
