   are transmitted using a BEEP profile [2].

   Throughout this memo, the terms "request" and "response" refer to the
   "methodCall" and "methodResponse" elements defined by the XML-RPC
   specification [1].  Further the terms "peer", "client", "server", and
   "one-to-one" are used in the context of BEEP.  In particular,
   Sections 2.1 and 2.1.1 of [2] discuss BEEP roles and exchange styles.
