Overview

XML Exclusive Canonicalization (c14n) for Nokogiri.

Classes mixin this module to implement canonicalization methods.

This implementation acts in two parts, first to canonicalize the Node or NoteSet in the context of its containing document, and second to serialize to a lexical representation.
