I submit that defining "access rights" in a protocol-independent way is
going to be extremely difficult. Therefore the proposal you forced me to
create will use email addresses which is slightly more tractable. Another
benefit will be shorter, simpler namespace URIs.

The idea that people will assign URIs hierarchically based on their HTTP
namespace has not take hold in practice although my specification will
support that for the rare occasions where it is useful. But consider, if
Andrew Layman makes a URN like this:

http://www.microsoft.com/msdn/xml/specs/schemas/

Consider how many levels of control are involved and how many
opportunities for screwing up persistence there are. The flatter the
namespace is, the better the chances of maintaining persistence.

Also consider ubiquity: some (arguably few) people have email addresses
but no web site.
