Since everything on an LDP server is an LDPR, seems unnecessary for the
client to tell the LDP server on a creation request that the resource is a
resource.  That is simply my point.  This only comes up when creating
something that is "more" than a plain old LDPR, such as a container.
Therefore you have to be explicit.  Though, the counterpoint is that if a
client would leave it unspecified on the request the server could guess
LDPC interaction model, maybe not what the client wanted but it should have
been clear in the first place.

I was trying to be clarify (I see clearly that didn't work) that there
isn't some expectation that clients can set the interaction model on a per
request basis, it can only be set on create (at least only way we have
spec'd it).
