Hmm, interesting. So, strangely enough, the datatype maps for the OWL 2 
RDF-Based Semantics entailment regime are not extensions of the datatype 
maps of the D-entailment regime in SPARQL 1.1 (as it is written now). 
This disserves to be pointed out to the SPARQL WG.

Note, however, that D-entailment (in SPARQL terms) does not support all 
XSD types either.
