I don't believe we are ready to close issue 5.15. My understanding was
that we would release the OWL Lite Working Draft but not consider the
set of features in OWL Lite finalized. In particular, I think my concern
(raised at the face-to-face) about whether OWL Lite should be something
that can be easily implemented in Horn logic or datalog is still valid.
As such, I am not prepared to say that local existential range
restrictions belong in OWL lite, and oppose closing 5.15.
