Okay, I think it is time to find the 'official' way how to=20
deal with WebServices in Cocoon. There are many implementations=20
around and this is rather confusing (at least for me).=20

I summarized all available implementations that I know and=20
added them to a new Wiki page:=20
http://wiki.cocoondev.org/Wiki.jsp?page=3DWebServices

Please add your usecases and what you need (use) in Cocoon to implement
it.

Take this as starting point in order to get a 'official' web service
integration in Cocoon and to give our users clear advice what to take.
