The reason "response" is in quotes is because this would be a response 
at the transport/transfer protocol level. When using HTTP, the 
MakeConnection SOAP messages is sent with the HTTP request, the SCA 
callback request message is sent back on the HTTP response.

It can be used with a WSDL req-response operation on the callback 
interface. This is similar to how WSDL req-res operation works when the 
wsa:ReplyTo is non-anonymous. In the case of req-res SCA callback 
operation, the message exchange will consists of 2 separate HTTP 
connection as follows:

1.1) Reference --> [HTTP req msg + MC] --> Service
1.2) Reference <-- [HTTP res msg + callback req] <-- Service

2.1) Reference --> [HTTP req msg + callback res] --> Service
2.2) Reference <-- [HTTP res msg (2xx) + empty entity body] <-- Service
