Adding GDL Extensions to an Existing GPD File

If you intend to add support for autoconfiguration to an existing in-box GPD file, you should:

1. Create the GDL file. The GDL file should have the *BidiQuery and *BidiResponse elements that correspond to the *Feature/*Option constructs, as specified in the PPD file. Note that you must add these elements only for features that require bidi information.

2. Include the GDL file as part of the driver-dependent file list.
