Interaction Modes in JAXM,JAX-RPC

Hello,
I have a bunch of doubts ,Kindy help
I understand that when two end points communicate they must agree upon two things
-Data Types (Type System)
-Interaction Modes/Styles/Patterns.
Interaction Modes
-----------------
JAX-RPC defines three interaction modes in Chapter 3,R012 in 0.9 Spec
1) synchronous request response
2) one way RPC mode
3) Non Blocking RPC
JAXM Defines Five Modes of Interaction ( See JAXM spec , 1.2 Scope )
1)Asynchronous Inquiry
2)Asynchrnous update
3)Synchronous Inquiry
4)Synchronous Update
5) Fire and Forget
Q1) Are these derived from http://www.w3.org/TR/xmlp-scenarios/ ?
Q2) The Client would know about the Service ('Data Types ') from the WSDL file .
How will the client know abt the *Interaction Mode* of the server ?
Or Am I missing something here ?
Thanks and regards
Mandan Happy
