Hi,

As I understand it, the proposal does not intend to keep a registry of the
URIs used for discovery (it is a parameter for a query using HTTP GET) and,
therefore, ALTO could mandate its own URI, in the same way the U-NAPTR
lookup defines the string to be queried.

The requirements on external registrations are essentially the same in both
cases (none, I think). My point is that an ALTO client would have to rely
only in queries aligned with the rest of the transport protocol, i.e.
plain HTTP(S), and not be required to include support for specific DNS
queries.

Be goode,
