Two concerns:

1) authority ID collisions
2) ID disputes

For example, if I send out that I've registered "MSFT" as my namespace ID
authority prefix (e.g.  <MSFT_ns1:blah MSFT_ns2:foo="bar"/> ), then I'm
likely to collide with Microsoft's preferred very short string authority ID,
since I imagine they'd want to use their stock index symbol. Assuming that
I'm correct, and a dispute arises, who resolves it? That's why I think you
need a central authority, or at least an arbitration board, which is more or
less the same thing.

Now, if you're asking me if the authority registry needs to be centralized,
I guess it wouldn't. However, there's really no need to 'look-up'
authorities in normal metalanguage processing.  All we're trying to do is
make sure that:
 1)elements and attributes have unambiguous names; 
 2) companies and individuals have the means (through the proper use of
their authority ID string) to easily create such names.

Good questions, Len. I'm forwarding this to the permathread. I hope you
won't mind.
