exactly. the page is not the namespace. i'm actually drawing a stronger
line between the page and the namespace. thats why i used the language i
did. i referred to the 'namespace' and the 'retrievable resource' at
the same URI. i guess i see a namespace as a completely different resource 
than the page. the page defines/describes/bounds the namespace, but i'm
not sure i see it as even a representation of the namespace. perhaps
i have a poor understanding of namespaces. 

an example of the potential problem:

<http://namespace.com> dc:creator "devon" .
<http://namespace.com> dc:creator "mike" .

i created the namespace. mike created the page. 
no one could tell from those two statements, however.

no, i understand the distinction between the resource and its representation.
again, i'm just not sure the page is a representation of the namespace.
