Re: [xml] c14n problem

[Aleksey Sanin <aleksey aleksey com>]

If you are refering to C14N specification [C14N] then you are right. 
However,
for exclusive c14n [Exc-C14N] (you are using "--exc-without-comments" 
option,
don't you? :) ) the story is different. The spec says that all "visibly 
utilized" namespaces
not rendered in the parent element need to be rendered (there is no 
mention of the
default 'xml' namespace as far as I can see!). In your example, 'xml' 
namespace is
visibly utilized by 'xml:space' attribute and it is not rendered in the 
parent.

It's not a bug as far as I can interpret the specification. If you have 
doubts then you can
ask this question in XMLDSig mailing list.
