Exactly. A namespace is just "punctuation", per se.

A namespace is not a vocabulary, even if a vocabulary may be
grounded in one single namespace.

Multiple disjunct vocabularies may all be defined in the 
same namespace.

A single vocabulary may include terms grounded in
different namespaces.

A namespace is not a doctype or schema.

A doctype/schema may use a single vocabulary grounded in a 
single namespace, or it may use several vocabularies, each 
of which have terms grounded in different namespaces.

Several doctypes/schemata may use the same vocabulary.

Namespaces are punctuation. Nothing more.
