Comments

To use this call, you must create all the datatypes, requests, and components which you would use if you were producing a complete file. But you do not have to fill in the values for the components not requested.

This approach only works if the translator was invoked by the program. In a standalone setting, this call always returns a one.

If comp is -1, then the function returns 1 if any component was requested. If req is -1, the function returns 1 if any combination of requests and components were requested.
