Subject: WSDL schemas update

Hi, all!
Following community demand for updating WSDL schemas to Recommendation
version of XML Schema, schemas were updated at the following locations:

Wsdl.xsd 		-	http://schemas.xmlsoap.org/wsdl/
Wsdl-mime.xsd	-	http://schemas.xmlsoap.org/wsdl/mime/
Wsdl-http.xsd	-	http://schemas.xmlsoap.org/wsdl/http/
Wsdl-soap.xsd	-	http://schemas.xmlsoap.org/wsdl/soap/

Schemas were also fixed in couple places to match verbiage of the WSDL
spec. They were reviewed and approved by spec authors. 
Please take a look and tell us if there are any problems.

Thank you.
