Okay, so, let's say I create a XML DSig extension where an ds:Signature
element is added as last child of cdl:choreography. Implementations of
this extension are required to ignore the cdl:choreography element if
the Signature is not valid. This would seem to contradict the semantics
of the cdl:choreography element since implementations are not allowed to
ignore it under these conditions. So making such a XML DSig extension is
not allowed. Correct?
