I suggested this to TimBL at WWW8 but he didn't buy it. My argument went
something like this:

1. Namespace URIs don't have to point to anything retrievable, they are just
unique identifiers
2. Some URI schemes might not be web-retrievable (eg "isbn:1-23456-789-0")
3. Some URI schemes *are* web-retrievable (eg http://www.megginson.com/ns/)
4. So namespaces URIs *can* point to something, though, such as a
human-readable description of the namespace, if they use a URI scheme that
is web-retrievable.
5. If this is done, how does one distinguish referencing the namespace from
referencing the file describing the namespace
6. My suggestion: come up with a new URI scheme that has the same
scheme-specific syntax as an http URI but that is only intended as a unique
identifier.

TimBL suggested there wasn't a distinction to be made (as did Rohit Khare
who cited Roy Fielding's PhD thesis). I'm still not convinced. Comments?
