I think pushing rather hard on a design that does not fully exist yet in saying "can't".  You have a suggested requirement.

Not RDF/XML per se, but that's it in the area of INSERT DATA so we might have an operation like LOAD INLINE (and multi part MIME? Bit messy).

This requires a service to manage the store service endpoint.  

I see that as putting language into the URI query string 

'http://store.example/?loadInto=http%3A%2F%2Fexample.com%2Fdata.rdf'

But again, what if there is no protocol engine?

A language enables "perform this script (ref file) on that endpoint".  The ability to record, pass around, reply is valuable.
