[XML-SIG] DOM ProcessingInstruction problem

[Jeff.Johnson@stn.siemens.com]

I came across an exception (see below) when calling core.Document.toxml().
I made a temporary fix to core.py which is at the bottom of this email.  I
don't know if the line I added is the way to fix the problem or if all
references to "_node.target" should be changed to "_node.data".  And please
don't forget about adding support for comments (or tell me why you won't).

Traceback (innermost last):
