What does RDF consider a namespace to be?

It appears to me that the XML namespaces document makes XML namespace
simply be the set of URI references that share a common prefix.  Therefore
all XML namespaces contain an infinite and unchanging set of URI

However, Concepts says that ''Some terms in these namespaces have been
deprecated, some have been added, ...''  which appears to indicate that the
names in the namespace can be changed.  Does RDF actually use a different
meaning of a namespace than is used in XML?

Other places in the RDF documents also seem to indicate that RDF considers
namespaces to have finite and changing sets of URI references.  For
example, Section 5.1 of RDF Syntax says

	The [RDF] namespace contains the following names only: 
	Any other names are not defined ....

Concepts says

	Vocabulary terms defined in the rdfs: namespace are defined in the
	RDF schema vocabulary specification ....
