Note that the current version only checks the relationships between the various parts of the WSDL, it doesn't really check anything in the schema sections yet. A couple of folks on the schematron mailing list are working on some XSD checking code, and it will be added to the validator when its done.<p> -8.5 <STRONG><A NAME="Q8_5">Is there a command-line utility that I can use to generate a WSDL File?</A></STRONG><BR> +8.7 <STRONG><A NAME="Q8_7">Is there a command-line utility that I can use to generate a WSDL File?</A></STRONG><BR> Yes - the IBM web services toolkit (WSTK) 2.3 (<A HREF="http://www.ibm.com/developerworks/webservices/";>http://www.ibm.com/developerworks/webservices/</a>) includes a utility called 'wsdlgen'.
