I know. I just diagreed with it. See:

This is substantively false. I built OWL-S systems that were quite  
intimately *a*ttached to wsdl, at least in the sense that they  
actively used WSDL and WSDL based services in quite a seemless way.  
You may disagree with the technical choices of HOW WSDL was  
incorporated (indeed, y'all prefer to modify WSDL documents; fine;  
that's an orthogonal point).

I assure you that companies such as Fujistu and Lockheed Martin  
understood the OWL-S use of WSDL to be connecting to Real Web Services.

But this is neither here nor there. SAWSDL is a fact. I didn't agree  
it was worth *my* effort, so I didn't give any! But y'all think it  
was worth yours, and you've accomplished something. Yay!

It's not like having hooks is *damaging*.

That's certainly possible. And even if it were fruitful "only" as  
marketing, that could justify the effort from a W3C perspective. I  
don't agree, but it's no skin off my nose. Really! I hope my  
disagreement is no skin off yours, either.

See my earlier message (which I think was the point of Matthias's  
post, not to dredge up old debates).
