Custom XMP Metadata
You can include custom XMP metadata in PDF output. You reference your own XMP file for a PDF publish action and the information it contains is output as properties of the resulting PDF. You can view the metadata in, for example, the Advanced Additional Metadata window in Adobe Acrobat.
* 
Custom XMP metadata is merged with default PDF XMP metadata and other configured document properties. The custom XMP metadata is overridden if the other two contain the same entries.
