Can you > describe why you think of them as two distinct things? Because of the definition that "RDF document - A serialization of an RDF Graph into a concrete syntax." From that definition, it sounds to me that the graph and its serialization are two different things. Now, my confusion may not stem from this, but rather the difference between an RDF document and RDF graph content. So, what you're saying is that the actual document isn't identified, the graph content is, universally? Perhaps I'm going to deep into corner cases but surely there are things that are specifically RDF Documents, perhaps foaf:PersonalProfileDocument isn't, so lets take as an example ex:ListofStuff rdfs:comment "An RDF Document containing a list of stuff serialized to Turtle" . Then there is @base <http://example.org/mylist> . <> a ex:ListofStuff . <#foo> a owl:Thing . ... Now, can http://example.org/mylist identify RDF Graph Content without a URI collision? As a final note, I think that sentences that begin with "Intuitively," in specs like this is a pretty sure sign of something that will miss the audience. Those who do find that intuitive will not need to be told, and those who do not will find it daunting. Is the understanding of RDF-MT necessary to write a compliant implementation of the specification? If not, it may appear intimidating to many developers.
