[xml] XML-Signature

[Aleksey Sanin <aleksey aleksey com>]

Hello, List!

Recently XML-Signature 
(http://www.w3.org/TR/2002/REC-xmldsig-core-20020212)
became a W3C recommendation.  I wonder does there exist an open source 
implementation of
it (based on libxml?) and if there is no one then will it be interesting 
to create one?
I know that there exists an Apache Java based library but I am looking 
for C or C++ one.

Thanks,

Aleksey.
