[VK] Would like to clarify that no matter what the internal state of the
reasoner, it could always report it's entailments in a standardized format.
For example, Fact++ doesn't need to share it's internal state to report OWL 1.1
inferences. It reports those inferences in a standardized format specified by
the OWL 1.1 standard.

[VK] My proposal is more along the lines of Deborah's proposal. The issue of
scope is real. Would propose that instead of throwing away the proposal
completely, we can figure out a limited and scoped standardization in this
