Dear List,
After starting to work with XML messages embedding XML signatures
I of course ran into validation problems due to namespace inheritance.
After some "googling" I found the cure and of course it was you guys who
had made it as well :-) A bit late in the process, but anyway. :-|
I mean this one: http://www.w3.org/2001/10/xml-exc-c14n# .
Still I'm not 100% sure how this scheme works. Am I correct
if I say that the existance of the URI above in "CanonicalizationMethod"
limits the outermost scope of name-spaces to the "Signature" element?
Does this also mean that the following is a bad design that will fail
to validate in most implementations:
<my:elem my:xmlns="htpp....">
<dsig:Signature dsig:xmxns=...>
<dsig:SignedInfo>
<dsig:CanonicalizationMethod Algorithm="http://www.w3.org/2001/10/xml-exc-c14n# ">
.
.
<Object>
<my:something_defined_in_the_ns_outside_of_Signature.....>
</Object>
</Signature>
</my:elem>
That is, should you redeclare the the ns associated with "my" _inside: of the
Signature declaration to be compatible with conforming systems?
MC & HNY!
