title: which xsd schema for wsdl 1.1 is the right one?
body: <p>I have found that there is a multitude of XSD files on the web that claim their targetNamespace is "<a href="http://schemas.xmlsoap.org/wsdl/" rel="nofollow">http://schemas.xmlsoap.org/wsdl/</a>". Naturally, there is one at "<a href="http://schemas.xmlsoap.org/wsdl/" rel="nofollow">http://schemas.xmlsoap.org/wsdl/</a>", but there is another one at "<a href="http://www.w3.org/TR/wsdl#A4.1" rel="nofollow">http://www.w3.org/TR/wsdl#A4.1</a>". And e.g. Oracle has at least 10 versions of wsdl.xsd in its SOA Suite 11g, all somehow derived from the xmlsoap.org or w3.org version.</p>
  
  <p>The problem is, all these various WSDL 1.1 definitions are mutually different!! For instance the schema at "<a href="http://schemas.xmlsoap.org/wsdl/" rel="nofollow">http://schemas.xmlsoap.org/wsdl/</a>" allows the "name" attribute on  and  for operations in the  sections, while the schema at "<a href="http://www.w3.org/TR/wsdl#A4.1" rel="nofollow">http://www.w3.org/TR/wsdl#A4.1</a>" doesn't allow that.</p>
  
  <p>So, which XSD schema for WSDL 1.1 is the right one?</p>
