get_xmp() returning None #20

I want to _add_ xmp to an existing PDF file which doesn't have xmp data yet. I 
tried opening the existing file:
>>> from libxmp import *
>>> xmpfile = XMPFiles( file_path="1.pdf")
>>> xmp = xmpfile.get_xmp()
>>> print type(xmp)
<type 'NoneType'>

I read on http://forums.adobe.com/thread/708717 that it does not seem to be 
possible to inject xmp data into an already existing PDF from their toolkit.

Thus, do I have to use something like acrobat to create the PDF first or is it 
in some way possible for python-xmp-toolkit to inject xmp?
