Absolutely right.
Furthermore, the term "SPARQL-DL" is not our invention. The name has its 
seeds in a OWLED '07 paper from Sirin and Parsia that introduced a 
subset of SPARQL for OWL DL. Our implementation basically is an 
extension of this query language wrt. OWL 2 on top of the OWL API.

Best,
Thorsten
