One can just add separate objects unconnected with the pdf content or marked 
content annotating the graphics object in a PDF content stream. Says in the 
PDF ref. 5th edition page 18. Little more from there: PDF provides means for 
applications to store their own private information in a pdf file. This 
information can be recovered when the file is imported by the same 
application, but it is ignored by other applications. Therefore, PDF can 
serve as an application's native file format while it's documents can be 
viewed and printed by other applications.
