Input for Requirement document

All,

Here are Fujitsu's input to Requirement document.
This may not be consistent with the Requirement
document Nokia provided before.

1.Synchronous request/response messaging.
    As discussed before, it is important to support
    this model, since SOAP is used with this model 
    in most cases.

2.Firewall consideration
    We want to realize the asynchronous messaging
    through firewall. This could be realized with Pull model.
    Example of Pull model:
        When PC inside firewall receives a message,
        it initiates a connection to sender every XX minutes
        to pull a message in sender's storage which was
        prepared for the receiver. Thus connection is
        always initiated from the receiver.

3.Client/Limited resource device consideration
    Pull model also helps Client or limited resource
    devices which can send a message, but can't 
    receive a message, to receive a message from others.
    Since these devices may not have static 
    IP address, nor capability to stand-by for incoming
    message.

4.Attachment support
    We want to make sure the spec is available to use
    attachment, and include such description.
    Eg. MIME, WS-Attachments

5.Consideration for other WS-XX spec
    As described in the charter, that the spec should be
    consistent with other WS-XX spec standardized 
    by standard body. And it might be appropriate 
    for this WG to consider consistency with WS-RM spec,
    if it doesn't violate any other's IPR.

Thanks,

Iwasa
