I use the time after today's super-short meeting to make some very minor comments on this very concise and informative document: cudos to the editors!

1)	time:before has domain and range time:TemporalEntity which time:after doesn't. I guess that time:after should have domain and range, too.

2)	There is a typo in the URI given in the OWL-2 reference [1]. The text is ok, but the href says http://www.w3.org/TR/turtle/owl2-quick-reference/#Built-in_Datatypes . I think that should be http://www.w3.org/TR/owl2-quick-reference/#Built-in_Datatypes

3)	Regarding ISSUE-125 and backward compatibility with OWL-1, there was a mail from Antoine Zimmermann where he said: "The standard Web Ontology Language is now OWL 2. Let us forget about OWL 1" [2]. So I think it should be safe to update the spec to use xsd:dateTimeStamp.
