The point I keep trying to make is that the properties like
"nature", "purpsoe", and "description", are properties <emph>of
the related resource</emph>, not of the namespace or of the RDDL
or of the directory entry.  T

No matter how hard I try I can't get worried.  A namespace
name names a namespace.  It can be used to retrieve a directory
which contains pointers to resources related to that namespace,
and descriptions of those related resources.  Those resources 
can include human-readable descriptive text, and can optionally 
be located right there in the directory.

The interpretation of '#Nature' is different depending on whether 
it's pointing into an XHTML file (whether it's a RDDL or not) or
an RDF schema or whatever.  I don't think there's room for
confusion.

It names a namespace.  That's not in question.  If dereferencing
the resource returns a namespace document, that's a good and
useful optional extra. -Tim
