Well, I used a wrong word. Not "cert" but "certs" :) The point is that 
you don;t know
the certs order in xmlSecKey. Nobody said that it'll be the same as one 
you've
specified in xmlsec utility command line :) For example, xmlsec-XXX 
might use
a hash table (per cert subject) to store the certs assotiated with a key.
