An XML namespace is just a set of names. According to the abstract model 
they have no semantic significance beyond that. By analogy, a function 
in a programming language is just a unit of code that takes inputs and 
generates outputs. Nevertheless, one SHOULD document functions in a 
programming language and SHOULD document one's namespaces. I see no 
contradiction between the acknowledgment that they have a very limited 
set of built-in semantics and the recognition that they typically 
represent a vocabulary with documentation.
