[ ] Decide proper schema definition to include as reference material.
I found this xml schema which contains the dateTimeStamp definition but I'm not sure if we link directly to that schema or not.
Within the schema, the targetNamespace field is "http://www.w3.org/2001/XMLSchema" and after reading the documentation, I'm still not sure which is more correct; referencing the 2009 version or the 2001 version.
I'm not sure too. Reading owl time in the documentation they reference to the XSD 1.1 normative reference (HTML document), but in the RDF representation seems that they use http://www.w3.org/2001/XMLSchema#dateTimeStamp

PR for #269
I couldn't find out the XSD schema for 1.1 so I changed the reference in 084ce900c to link the normative definition. Could be https://www.w3.org/TR/owl-time/#time:inXSDDateTimeStamp another better option ?
