I had a look at my previous analysis [1] on owl:DataRange in OWL 1 Full. Based 
on this, I think that it's reasonable to make owl:DataRange equivalent to 
rdfs:Datatype. More precisely: I suggest to define the class extension of 
owl:DataRange to equal IDC, which happens to also be the class extension of 
rdfs:Datatype. Technically, there is no problem to follow this approach, since 
OWL 1 Full actually does not say what the class extension of owl:DataRange is.

I have made a few notes on the suggested changes in [2].
