Web Services Inspection Language (WSIL) is a service discovery mechanism that is an alternative to UDDI as well as complementary to UDDI. WSIL can be generated at any point in the Web service development cycle once the WSDL file for the Web service has been created.
WSIL helps synchronize this process by maintaining references to WSDL URLs. Web services tools that process WSDL documents - such as the Web Service Client and Creation wizards - will accept a WSIL document as a substitute for WSDL. This allows you to create a standardized WSDL reference (WSIL) document in your project during Web service client generation, then at a later time easily regenerate the client from that reference document. No copies of the WSDL or WSDL URLs are required.
You can generate a WSIL file from a pre-existing WSDL file or during Web service creation or consumption.
