/**
* Implements " Exclusive XML
* Canonicalization, Version 1.0 "
* Credits: During restructuring of the Canonicalizer framework, Ren??
* Kollmorgen from Software AG submitted an implementation of ExclC14n which
* fitted into the old architecture and which based heavily on my old (and slow)
* implementation of "Canonical XML". A big "thank you" to Ren?? for this.
*
* THIS implementation is a complete rewrite of the algorithm.
