Re: does DAWG actually have time to do WSDL?

Ok, I lied.

Here's a response now :)

Ok.

I guess it's more a sense from comments I've seen. Significant features 
and questions of semantics seem under debate. *however*, now that I 
think about it, all we need to care about is the syntax, for protocol 
purposes.

Syntax, primarily. I don't think there's any semantic ones.

Ah ok.

What would make the best WSDL is if we have a plausible XML Scheme 
element for the input (the query) and the output (the results format). 
With these, the abstract portion of the WSDL is trivial, as is 
certainly the SOAP binding.

If the syntax is reasonably static, then yes, we have what we need. 
Thanks.

Great.

Er...well, not exactly, right? Yes there is functionality that used to 
be in QL language that now will only be available in the protocol, but 
moving them out of the query doesn't create a dependancy between any of 
the remaining aspects of the QL and the protocol, does it? Am I missing 
something?
