<p>A common way to canonicalize XML which could be used is &w3canon;. It was decided not to use <cite>Canonical XML</cite> for the following reasons:</p>
<ul>
<li>Implementing it is quite some effort and not all XML libraries come with an implementation.</li>
<li>It is sensitive to the relative ordering of the elements. The relative ordering of children in disco#info &lt;query/&gt; elements does, however, not matter.</li>
<li>It is sensitive to the relative ordering of the elements. The relative ordering of children in disco#info &lt;query/&gt; elements, however, does not matter.</li>
<li>Several children of &xep0128; data forms are deliberately ignored, like instructions and other descriptive text. The descriptive text is not relevant for the information is being conveyed.</li>
</ul>
<p>Thus, using <cite>Canonical XML</cite> would require additional, non-trivial software support and still require non-trivial additional canonicalization rules.</p>
