Use this method with AddExternalValidFormDef and KeepExternalValidFormDefs when you want to tell FORMS which form definition(s) to use when trying to identify the form. ClearExternalValidFormDefs clears the list of form definitions that have been added using the API, so that only the ones specified in the job description remain. See code example.
