[XML-SIG] losing cdata tag

[Paul Tremblay]

I have copied the code below from python cookbook, but it is not
working. Specifically, the "def startCDATA(self)" method does not
get invoked.

Since this method does not get invoked, my cdata is not getting
put between the right tags. That means my output file is no
longer valid xml, and I cannot parse it again.

Thanks

Paul
