Issue: The SDL interface examines GUID, version, format name, and language to determine if an output format can be saved into the database.  This is insufficient as we have multiple outputs of the same format that use the same language and format.   

Current workaround: Create multiple output formats.  This is not sustainable.

Business scenario:  External data drives generation of output using the same source and language.  Post processing handles the placement of the unique (product part #) metadata.  Single source (DITA XML content) from which multiple outputs for the same language are created (Part #1, Part #2, Part #3). 

Request: Allow users to provide additional, unique meta (at the publication language level) to allow for generation of multiple output formats within the same publication using the same language/version information.  This will allow for a one-to-many relationship of publication (1) to parts (many).
