Dear Jeremy:
Good catch.
The wording in Semantics concerning the makeup of RDF datasets was always
intended to be explanatory, not normative. It has been replaced by text
that is more clearly explanatory in the current editors' draft at
https://dvcs.w3.org/hg/rdf/raw-file/default/rdf-mt/index.html#rdf-datasets
Please take a look at the new version and respond to
public-rdf-comments@w3.org indicating whether this change meets your
approval.
