How do I validate WSDLs and SOAP responses?

I am looking to build web services开发者_JAVA技巧 using SOAP. What standards should I follow for formatting WSDLs and SOAP responses and what tools are available to verify I am using the correct standardized formats?

I was thinking something along the lines of W3C's HTML validator but for SOAP and WSDLs. Does any such thing exist?

You should look at the WSI tools (or other tools that can run the WSI compliance tests). You can also do xml schema validation of the soap messages against the WSDL/XSD that you have so that you can confirm that your service does actually conform to its description.
