Subject: Fw: WSFL, IBM, and WSDL

Oh I also forgot to mention about WFSL ... it kind of also tells you in what
order to call different methods of a web service. If you have a shopping
cart service with methods like "getCart", "addItem", "checkOut" etc. It will
not make sense to try to checkOut before at least calling "getCart" right?
These things are kind of missing from WSDL. Although they can be easily
added there. They did not have to come up with a new thing for all the
features that are in WFSL. There is a very good article talking about some
problems within WSDL in the June/July issue of XML magazine
Check it out.
