[erlang-questions] Diameter Relay Agent

[Anders Svensson]

The RFC 4006 dictionary presumably doesn't return the relay identifier
from id/0. Even it it did, messages aren't decoded in the same way by
a relay. The only decoding that's done is to split the message into
AVPs, so it's the avps field you want to look in.
