<h2>Canonical XML / Exclusive Canonical XML</h2>
</div>
<p>
Both <a href="http://www.w3.org/TR/xmldsig-core">XML Signature</a>
 and <a href="http://www.w3.org/TR/xmlenc-core/">XML
Encryption</a>
 use XML Canonicalization standards to produce canonical form of the original
XML document. Except for limitations regarding a few unusual cases, if two
documents have the same canonical form, then the two documents are logically 
equivalent within the given application context. Implementation of both these
standards were included in libxml2 library because these algorithms could
be interested for other applications as well.
