FAQ on Reply Pattern Support

[Tom Rutt <tom@coastin.com>]

The following is a proposal for a FAQ on reply pattern support.

FAQ:

 

'Why several reply patterns.?

 Answer:  Because there are different use case and deployment scenarios 
and different WSDL MEPs/operations, limiting to just one reply pattern 
will adversely affect its usage and importance of the protocol.

For example, a Sender behind a firewall may prohibit incoming requests, 
as required by the callback reply pattern  and, hence, needs to use some 
kind of polling mechanism to poll for the message.

Similarly a one-way WSDL operation cannot use a Response pattern as it 
is against the WS-I Basic Profile 1.0 for a one-way operation to have 
a SOAP envelope in its response. Because of such common, yet different 
use cases, different reply patterns have to be supported by WS-Reliability."
