Another gotcha - some of the WSDL compilers only work with specific versions of XML Schema. The current ZNG WSDL uses the 2001 specification. Some of the tools (e.g. the betas of .NET) only worked with the Sept or Dec 2000 XML Schema drafts (i.e. you may need to tweak xmlns:xsd=" http://www.w3.org/2001/XMLSchema" to point to earlier versions).
