Actually, I'd prefer to see it become:

naming authority + resource ID

With the publisher ID subsumed perhaps into the opaque
string of the resource ID.

The way I see it, the publisher info may or may not be
appropriate (eg. some schemes wont have a specific
publisher ID), but the naming authority is needed to allow
us to experiment with more than one scheme and we'll
definitely want to be able to do that.

Some schemes will contain DNS hooks for server location,
some will be easily computable, some will be more easily
readible, some will be strings of numbers, etc. The naming
authority allows a client author to write code to decide
right away if this is something it can handle, or needs to
bounce/hand to a proxy server/whatever. The actual
dereference is the second step that follows this first one
in this world view. Without the naming authority I don't
see how you can decide what to do next.
