At least by the desired sense noted in the topic of the mail message "literal has datatype D". A plain literal had datatype http://www.w3.org/TR/rdf-plain-literal/ which isn't any datatype other than itself. It certainly isn't and xsd:date. Is what's trying to be said that a certain string should be interpreted as a certain datatype? But if that's the case, why not just write it "certain string"^^datatype? (if it is malformed, you will get an inconsistency, which is good!)
