CentraSite builit in WSDL is not valid?


I needed to use this imported service to load XSD’s from a URL.

I am getting this error when validating the wsdl:

File http://myserver:53307/wsstack/services/ImportXsdService?wsdl is not valid.
attribute ‘part’ in extensibility element ‘’ refers to part ‘importXSDviaAttachments’ which could not be found in message ‘importXSDviaAttachmentsMessage’
Error location: wsdl:definitions / wsdl:binding / wsdl:operation / wsdl:input / mime:content / @part

Can you help identify what is wrong?
