[XML-SIG] binding an unbound namespace prefix

[Keith Beattie]

Hi all,

I'm trying to parse a string which is a segment of xml (in order to 
canonicalize it) which doesn't have all it's namespaces bound in the segment 
I'm trying to parse.  How do I pass the namespaces into minidom.parseString(), 
or Domlette.NonvalidatingReader.parseString(),such that they'll be happy with 
the 'unbound prefix'?  I hoped to see an nsdict kw arg or some such, but no 
luck.  Is building the dom myself the only way to do this?

Thanks,
ksb
