While preparing yet another attempt at text to suggest for my LC comment about using RDF to describe named graphs, I noted an error in the math in the LC documents.
In concepts we read:
[[
An RDF dataset is a collection of RDF graphs, and comprises:
• Exactly one default graph, being an RDF graph. The default graph does not have a name and may be empty.
• Zero or more named graphs. Each named graph is a pair consisting of an IRI or a blank node (the graph name), and an RDF graph. Graph names are unique within an RDF dataset.
]]
In semantics we read:
[[
An RDF dataset (see [RDF11-CONCEPTS]) is a finite set of RDF graphs each paired with an IRI or blank node called the graph name,
]]
These are different.
In particular.
Concepts allows:
<eg:a> {}
<eg:b> {}
And semantics does not, since the empty graph is not paired with a single IRI or blank node.

Sorry for noticing this very late.
