I have an ebXML message receiving party that is hassling me for sending
the wrong canonalization transform in the envelope. Also he is not happy
for the lack of namespace in the signature element and sub elements.
=20
Excuse me for asking, but I=92m not to good at the secure xml syntax =96
yet=85
=20
So, here are some simple questions for the gurus on this list:
1) Is there a difference between the cannonalization algorithm
http://www.w3.org/TR/2001/REC-xml-c14n-20010315 and
http://www.w3.org/2001/10/xml-exc-c14n# (which I seem to get from XMLSec
when specifying c14 without comments)? Why the =93#=94 any not an exact
number?
2) There is still now way of specifying a namespace prefix in XMLSec?
=20
Thanks,
