So I've taken a walk through c14n.py and that code isn't getting called 
by my counter-example (of the c14n'ing the sub-node).  It looks like 
_sorter (rather than _sorter_ns, which will do the right thing) is being 
used for sorting those inherited NS attrs at line 324.

I'm still digging at how to fix that, but should I submit a new bug at 
http://sourceforge.net/projects/pyxml/ ?  (I just created an account but 
otherwise I'm a newbie when it comes to contributing to SF projects). 
If so, I assume it would be under the DOM category?

Thanks,
