In most cases, you would not want the 'URN for a certain document' BUT
you would want the document itself. This is where 'resource discovery'
systems are useful. Ie you would not search for URN <foo:baar> but a
document AAAAA by BBBBB from CCCCC (since you do not know the URN).

Then, with X responses from your resource discovery system, you can then decide
which is the correct document and 'click on the URN' to get it resolved and
retrieve the document.

The URN working group needs to concentrate on the resolution step.

There will be plenty of 'value-added' resource discovery system available
once the resolution mechanisms are in place.

Cheers... Renato
