Re: SOAP/XML Protocol and filtering, etc.

The message broker design pattern needs "something" outside the message
payload (e.g. HTTP or MIME headers) to facilitate dispatch functions. The
alternative requires message brokers to have intimate knowledge of each 
message payload.

far better for the SOAP-specific message broker to have intimate knowledge
of the SOAP-specific payload, than to have the SOAP-specific message broker
to have intimate knowledge of the HTTP-specific request header.

also, far better for the SOAP-specific dispatching tags to be part
of the SOAP-specific payload which is supposed to be independent of the
protocol being used as a substrate for SOAP, than to have to supply this
dispatching tag in a different way for every substrate protocol.
