Hi, Back in Sept 2011 Frase and Gordon had a discussion concerning negative expressions in binding keys ( http://mail-archives.apache.org/mod_mbox/qpid-users/201109.mbox/%3C4E647F62.5020205%40redhat.com%3E )
The conclusion was that it's not possible and that an xml exchange might provide the required functionality. I would like this feature for a topic exchange (the discussion above concerned specifically header exchanges) and wonder if the situation is still the same? I have not been able to find any other trace of this being done/documented. Failing the option of negative matching, a workaround I can think of is to route all messages to a "triage" topic exchange, read all messages I _don't_ want to a queue which will simply discard them, then use the "alternate_exchange" option to route any remaining messages (the ones I want) to another exchange where they can be managed as required... however this setup seems a bit of a kludge.
