M&S discusses the concept of a 'model' or 'graph' aka context
aka StatementSet - essentially being a set of statements.  Unfortunately
it doesn't make any mention of this concept in the section 5.

Thus this concept does not have to be introduced to RDF, but it does
need to be better defined.

For my money a lump of RDF/XML or N3 represents a set of Statements and
we can talk about whether a statement is a member of that set or not,
something I find clearer than talking about whether a statement is
'asserted' or not.

N3 introduces a syntax for embedding the respresention of such a set
of statements (N3 calls them contexts) inside the representation of another,
a feature RDF/XML current lacks.
