1749        <p>The value of the <code>xml:lang</code> attribute (either the
1750        <code>lang</code> attribute in the <code>xml</code> (i.e.
1751        <code>http://www.w3.org/XML/1998/namespace</code>) namespace, or

1755    
1756        <p>For historical reason, there are two attributes applicable to HTML
1757        elements to specify language information of an element: <code>lang</code>
1758        and <code>xml:lang</code>.  In HTML documents, only <code>lang</code>
1759        attribute in no namespace is allowed and take effect; the
1760        <code>xml:lang</code> attribute in no namespace is ignored in HTML
1761        documents.  In XHTML documents, both <code>lang</code> and
1762        <code>xml:lang</code> attributes are allowed.</p>
1763    
1764        <p>In general, <em>only the <code>lang</code> attribute</em> need to be
1765        specified for an element.</p>
1766    
1767        <p>If both <code>lang</code> and <code>xml:lang</code> attributes are
1768        specified on the same element, their values must be the same value.</p>
