What I am concerned about with the revised figure, is that handlers appear to be
an integral part of XMLP protocol/specification. There is a difference between
handlers being invoked automatically by processors (I am ok with that), and them
still living in "protocol space" rather than "application space". I may not have
been your intention, but this is how I am reading the revised figure.

What about XMLP Service ? This would fit nicely with the forthcoming workshop on
Web Services...
