Why namespace for wsdl is not "http://www.w3.org/wsdl"?

WSDL is specified by W3C. Isn't it better that the namespace is something like "http://www.w3.org/wsdl" ?

Anyone can tell me about the background or history about "http://schemas.xmlsoap.org/wsdl/" ?

Interesting thing. Web Services Description Language (WSDL) Version 2.0 Part 1: Core Language refers in section 1.4.4 Prefixes and Namespaces Used in This Specification to wsdl as http://www.w3.org/ns/wsdl.

Dan

Seems when WSDL 1.0 (Sept. 2000) was first developed by IBM, Microsoft and Ariba, W3C was not involved, so these giant corporations happened to invent a namespace neutral to anyone of them. (neither "http://www.ibm.com/..." nor "...microsoft...") I guess.

And the namespace doesn't change to "www.w3.org/wsdl" until W3C has finally got the copyright of wsdl 2.0.

Maybe this explains.
