My proposal is to accept Holger's suggestion of moving from
owl:Datarange to rdfs:Datatype.   The resolution would be to eliminate
owl:Datarange in favour of rdfs:Datatype.

Yes, I believe that Holger is asking to eliminate owl:Datarange as
unneeded and replace it by rdfs:Datatype in OWL Full.

I don't think that there is any interaction between this and infinite
abstract domains.
