svbscribe/notify scenario

[ Note from the moderator: I have changed "subscribe" into "svbscribe"
  in the subject line because our mailing list manager thinks it's a
  subscription message otherwise, and resent the message. ]

Hi all,

I would appreciate any help in the following two issues:

Are there any documents describing the differences between SOAP 1.1 and SOAP
1.2 as well as between WSDL 1.1 and WSDL 1.2?

I would like to implement the following subscribe/notify scenario:

A web service requestor subscribes to a stock quote web service for
receiving the quote for a specific stock at periodic time intervals. This
means that rather than a requestor pushing request messages continuously to
the
provider, the requestor subscribes once to this service and then the
provider periodically pushes the service responses to the requestor.

How is this implemented using tools such as Axis, IBM WSTK, Sun WSDP or MS
.NET?
And how do you describe such as a service in WSDL? As a service which
supports two operations: one for the subscription and another for the
notification?

thank you in advance,
Thomi
