Some remarks to telecon agenda item:

> o PROPOSED: close (as RESOLVED) Issue 29 
>   (ser-defined Datatypes: owl:DataRange vs rdfs:Datatype) 
>   as per

In the cited mail, Peter proposes:

>  4. In OWL Full, owl:Datarange is deprecated 
      (and made equivalent to rdfs:Datatype).

Question 1:
Why should 'owl:DataRange' only be deprecated in OWL-Full? I would rather
read this as "deprecated in the RDF syntax", independent on the respective
OWL dialect.

Remark 2:
Deprecation is probably ok, if it is meant in the way of: "Do not use
'owl:DataRange' in new ontologies, because there is a preferred way to
express data ranges.". But note that there will probably be always old OWL
ontologies around (both DL and Full), which contain datavalue enumerations
of the form:

  _:x rdf:type owl:DataRange .
  _:x owl:oneOf ( d1 ... dn ) .

So, deprecation in the meaning of "Will be dropped in the future." is
perhaps too drastic.
