Overview

A namespace is an object for resolving identifiers in scope denoted by a base URI to a full URI. For example,

rdfs = Namespace.new( "http://www.w3.org/2000/01/rdf-schema#" )
rdfs.comment # => "http://www.w3.org/2000/01/rdf-schema#comment"

There is no checking that the resolved name is known in the defined namespace (e.g. rdfs.commnet will work without a warning)
