Hi!

Again one of these overly late comments. :)

According to Section 5.8 of the Structural Spec [1], it is possible to declare datatypes:

  Declaration( Datatype( DT ) )

I can also see a mapping to RDF for this construct in Table 1 of the RDF Mapping [2], and a reverse mapping in Table 7 [3]. 

I do not understand why this is supported in OWL 2 DL. We do not allow for things like giving names to datatype restrictions, right? Or do I miss something?

Best,
Michael
