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

https://www.w3.org/2015/spatial/track/issues/169

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

https://www.w3.org/TR/xmlschema11-2/#nt-dateTimeRep
https://www.w3.org/TR/xmlschema11-2/#nt-gDayRep
https://www.w3.org/TR/xmlschema11-2/#nt-gMonthRep
https://www.w3.org/TR/xmlschema11-2/#nt-gYearRep

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).
