I am not even sure whether the RDF Datatype entailment would generate equality for these two, simply because there is no notion of derived equality there. In the case of OWL, and even the minimal RDFS+OWL stuff, ie, OWL RL, the situation is different: if one looks at Table 8 in[2], it says:

Doh. The one I wanted to quote is:

dt-eq		T(lt1, owl:sameAs, lt2)	for all literals lt1 and lt2 with the same data value

although the other one is also relevant.
