New WS-X Specifications (BEA)

["Chiusano Joseph" <chiusano_joseph@bah.com>]

I'm not sure if anyone has seen this recent announcement - and if it has
any significance for us at all beyond general awareness.

BEA recently released 3 "WS-X" specifications:

   WS-Acknowledgement
   WS-Callback
   WS-MessageData

More details:
  
* WS-Acknowledgement: Designed to support reliable message exchange
between services by providing for at-least-once and exactly-once SOAP
message transfer guarantees;

* WS-Callback: Used to dynamically specify where to send asynchronous
responses to a SOAP request;

* WS-MessageData: Enables the re-use of meta-data about a message across
SOAP extensions;

I find it interesting that although BEA was an author of
WS-ReliableMessaging (part of GXA), they have gone off and created their
own reliable messaging specification (WS-Acknowledgment). Like
WS-ReliableMessaging, WS-Acknowledgment is also *very* similar to
WS-Reliability.
