public abstract class Canonicalizer20010315Excl
extends CanonicalizerBase

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.
