Re: draft response for LC comment 62 JM1

Until our naming issue is solved, the exact relationships of OWL DL,
Full, FS are still a bit fuzzy and not 100% clear in the current
documents. Also, your first sentence also suggests some sort of a
primary role of syntax over DL:-(

May I suggest a slight re-write? Like:

[[[
Some naming of data ranges could be permitted in the Direct Semantics of
OWL 2, but one has to be careful about creating data range loops. The WG
did not explore adding this functionality and hence adding this extra
syntax and extra complication to the functional syntax.

In the RDF syntax, and hence in the RDF bases semantics of OWL 2, it is
of course possible to "name" a node that corresponds to a data range.
This IRI could be used just as any other datatype/class IRI in the RDF
based semantics OWL 2 with no problems.

So you are not missing anything, at least so far as the functional
syntax is concerned.
]]]

Cheers
