best way to publish webmethod parameters and return data

[Enda Mannion]

My webservice methods take a string as a parameter and all return a string
i.e c# string. The strings are actually XML files. So the string parameter
to my web methods are xml files and I have a schema file for each of these
strings but I would like to find a way to easily publish these schema files.
I know how to access the wsdl by providing a ?wsdl to the web service url.
Is there a way to reference the xml schemas in the wsdl so to easily publish
them to clients. They need to access to schemas to use my web service.


Thanks,
