I guess I'm not sure what still needs to be nailed down or what is gained
from answering the question of whether a graph is an information resource or
not.  It seems orthogonal to the HTTP update protocol definition since the
protocol only defines how to interact with RDF graphs over HTTP.

This seems to suggest that some interpretation of http-range-14 is a
necessary part of the HTTP update protocol and I think this is more trouble
than it is worth and beyond the scope of the document (which is about
interaction and not interpretation).

The use of the term 'information resource' was only meant to align with the
terminology used in the AWWW rather than to ascribe any formal definition
beyond what is implied in the current SPARQL specification: that graph IRIs
identify graphs that are represented by RDF graph syntaxes (and thus can be
manipulated over HTTP).
