Why is the 'qpid.' prefix used here?
I could understand that being used in an argument name to the 0-10
arguments map on message.subscribe (since it is a qpid specific 0-10
extension). For an explicit link level property however it seems odd and
unnecessary (since the entire address syntax is qpid specific).
There may be a need to allow different kinds of filter to be specified
also. Having a filter option that could be a nested map (and would thus
allow some type annotation to be added if needed) might therefore be a
good idea.
