The DNS is very good in giving you data back from for example a query
about a hostname (given a specific name) which handles a service.
We do it today with MX records.

DNS should NOT be used for resolving documents, i.e. the whole URN,
only the NA. The rest (or global searches) should be done with a
protocol suited for that...and this is exactly what we propose
as one scheme for resolving a NA to the service used.
