Description:

Reported by bparsia, May 17, 2007

One problem with OWL 1.0 is that it left undefined how to refer to XML schema based datatypes in 
an interoperable way. Basically, we need a canonical way to associate a URI with a type in an xml 
schema document.

Here is an analysis:
   http://www.w3.org/TR/swbp-xsch-datatypes/

OWL 1.1 allows users to define datatypes inside an OWL 1.1 ontology, but does not define how to 
refer to an external datatype, nor does it use standard XML schema syntax.

OWL 1.1 should pick and mandate a solution to referring to external user defined datatypes.
