Re: Weigh-in please - Template format: XML and/or Compact Notation

For this purpose we proposed using FAST encoded messages. This was initially part of the SCP draft. And if it don't find its way back in, I guess we'll have to create yet another specification: FAST Template Exchange Protocol (TEP) or something. The merits of such a protocol is not just space efficiency. FAST encoded templates mean one parser less to include in the execution path of your application.
