[XML-SIG] Two minidom patches

[Andrew Kuchling]

I've submitted two patches to minidom.py using the Python project's
patch manager.  (Should such patches be submitted to the PyXML patch
manager, or the Python one?)

https://sourceforge.net/patch/?func=detailpatch&patch_id=102485&group_id=5470
[ Patch #102485 ] minidom.py: Check for legal children

https://sourceforge.net/patch/?func=detailpatch&patch_id=102492&group_id=5470
[ Patch #102492 ] minidom/pulldom: remove nodes already in the tree

Anyone want to review them?
