FYI: IBM/MSFT whitepaper on secure, reliable, transacted Web services

This whitepaper documents the Web services platfrom from IBM/MSFT's
point-of-view:

ctedWSAction.pdf

You may need to join the lines assuming SMTP breaks it up. The paper
is available somewhere on the MSFT site as well.

I personally think its a nice document that explains the role of
the key WS-* specs that IBM/MSFT/others have published in supporting
the business requirements of secure, reliable, transacted interactions.
Of course I'm not exactly unbiased in my view; YMMV.

Sanjiva.
