+Summary: Compilation of WSDL file fails
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+
+wsdl can't generate a proxy class from a WSDL file for the OPC XML-DA
+webservice. This is the major standard for webservices in automation.
+Unfortunately I am not (yet) an expert in mono or .NET in general, so I was
+unable to track down the problem or use the debugger. 
+
+The WSDL file under http://www.rzg.mpg.de/~michel/SOPCWeb.wsdl is a WSDL
+file from a specific vendor (Siemens). When I try WSDL files from other
+vendors the error is the same. The WSDL-to-C compiler from gSOAP and  
+MS VisualStudio can compile it. 
+
+I guess it is a type conversion problem or the unability to process untyped
+data. 
+
+Steps to reproduce the problem:
+1. try  "wsdl http://www.rzg.mpg.de/~michel/SOPCWeb.wsdl" or any other
+OPC-XML-DA WSDL file. 
+2. 
+3. 
+
+Actual Results:
+
+Error: System.ArgumentNullException: Argument cannot be null
+in <0x0010e> System.Convert:ToType (object,System.Type,System.IFormatProvider)
+...and the stack of its callers
+
+Expected Results:
+
+A webservice proxy class
+
+How often does this happen? 
+
+with files conforming to the OPC XMLDA-1.0 specification:
+
+http://opcfoundation.org/webservices/XMLDA/1.0/
+
+Additional Information:
+
+when you first download the SOPCWeb.wsdl file, the
+
+assertion `hash_table != NULL' failed
+
+will disappear (maybe another bug)
