[xmlsec] xml digital signatures

[Aleksey Sanin]

xmlsec library expects a "signature template" as an input. Then it
calculates digests and signature, adds calculated values and all other
necessary information (e.g. key names, certificates) to the template
and this makes the result "signed document".

As far as I can understand your situation, you are writing signature
application yourself thus you have to define what do you want to sign
and do all the work yourself.
