3/ OWL will include all XML Schema built-in non-list simple types, using 
the canonical URI reference for them.

Exclude xsd:QName, xsd:ENTITY, xsd:NOTATION

Also exclude xsd:duration, because it has no well defined canonical form, 
and equality is not well-defined.

Caution would suggest excluding xsd:ID and xsd:IDREF since they seem to be 
about xml validation rather than lexical to value mappings.

If we include xsd:float, xsd:double and xsd:anyURI we should be aware of 
issues to do with equality that are unresolved. [3]
