(I cc Greg explicitly, because that is directly relevant to the service
description part which is his baby...:-)

another issue that, at some point, we will have to address... though
this is probably not part of the entailment document per se...

The issue is how a system broadcasts to the world that it can or cannot
handle certain profiles. From your document's point of view it is of
course correct to say that EL, QL and RL profiles are automatically
handled by referring to the Direct and RDF-compatible semantics. But
somehow, somewhere, I as a user would like to know whether a specific
endpoint can handle, say, EL only and not the full Direct Semantics (ie,
the DL profile, so to say). My gut feeling is that we may have to have
some extra vocabulary in the service description part...
