From config-interface to WSDL??

[Guadalupe Ortiz]

How could I add documentation elements automatically to the WSDL file. I mean, the wscompile tool reads the config.interface.xml file and automatically generates the WSDL file. How can I add the documentation? Should I open manually the WSDL file generated and add it? Or can I place it in some way into the config-interface.xml file and the wscompile will add it to the WSDL file automatically?
Any help grateful, thanks-in advance
