<p>The <dfn id=xml-version><abbr>XML</abbr> version</dfn> of a node is 
the <abbr>XML</abbr> version of the document to which the node belongs.
For a <code>Documemt</code> node, the <abbr>XML</abbr> version
of the document is the value of the <code>xmlVersion</code>
attribute.  For a <code>DocumentType</code> node whose 
<code>ownerDocument</code> is set to <code>null</code>,
the <abbr>XML</abbr> version of the document is <code>1.0</code>.
For any other node, the <abbr>XML</abbr> version of the document
is that of the <code>Document</code> node contained in the
<code>ownerDocument</code> attribute of the node.</p>
