Unary User Defined Datatypes: Issues
Some Key Email threads

Some context for this design comes from the Protégé 3.x implementation, discussed at http://protege.stanford.edu/plugins/owl/xsp.html
ISSUE-31: Canonical URI for externally defined datatypes
This issue is concerned with referencing XML schema definitions from within OWL RDF/XML, as discussed in this SWBPD WG Note.
ISSUE-71: Create datarange of literals matching given language range
ISSUE-74: Use the xsd namespace for the facet names
E.g., why is

ISSUE-11: Specification of which facet is being restricted in a datatype restriction is missing

Additional Items (Potential Issues)
- The Structural Spec and Functional Syntax document itemizes a set of supported facets but does not compare that with the complete set of constraining facets in XML Schema (whitespace and enumeration are omitted).
- The RDF/XML mapping document does not itemize the acceptable facets.
