The Diameter base protocol specifies mechanisms whereby a given realm
may advertise Diameter nodes and the supported transport protocol.
However, these mechanism do not reveal the Diameter applications that
each node supports.  A peer outside the realm would have to perform a
Diameter capability exchange with every node in order to discover
which one supports a required application.  This document describes
an improvement using an extended format for the Straightfoward-NAPTR
(S-NAPTR) Application Service Tag that allows for discovery of the
supported applications without doing Diameter capability exchange
beforehand.
