Input validation against xsd in connector


I would like to know whether webmethods has built in mechanism of validating every SOAP request against its xsd.

I have created Webservice Descriptor(Provider) and I don’t want to do the input validation inside my service, instead I would like to depend on webmethods to filter the requests at connector which doesn’t adhere to corresponding xsd as per wsdl definition with out any performance bottleneck.

I guess this is the basic requirement of any Webservice provider and webmethod should aslo support it with out any overhead involved and it should be transparent, experts please help me in this regard.
