Subject: OWL-Time - ISSUE-169: Section 7, DateTime Description

The valid values for the fields – including bounds - in a compact DateTime, and also gDay, gMonth and gYear are specified through a lexical pattern in the XML Schema specification – see

xsd:dateTime and xsd:dateTimeStamp are built in to OWL2, and most OWL processors enforce this directly.

No need to say anything in the OWL-Time document (though added hyperlinks to the relevant position in the XSD Datatypes spec).
