I noticed that the id= attributes in the kiwix-generated library.xml file are the UUID of the zim file as contained in the zim file header.

However, it appears there is a quirk in the library.xml that causes the third group of the UUID to be repeated? Is there a reason for this, or is it just a bug?

wikipedia_gn_all_01_2013.zim
Zim UUID (as parsed by my zimpy.py):
c0c9693a-4ec4-b7bf-d8cf-0bca9d7f363f

library.xml id= field:
<book id="c0c9693a-4ec4-b7bf-b7bf-d8cf0bca9d7f363f" path="../wikipedia-z
im/wikipedia_gn_all_01_2013.zim"

(b7bf is repeated)
