* Any of the XHTML document type declared or used will be converted into its HTML 4.01 counterpart,

* <dl>
* <dt>"<code>none</code>"</dt>
* <dd>Not to emit any dococument type declaration.</dd>
* <dt>"<code>compatible</code>"</dt>
* <dd>The HTML 4.01 Transitional (exploiting MSIE shortcut).</dd>
* <dt>"<code>strict</code>"</dt>
* <dd>The HTML 4.01 Strict document type.</dd>
* <dt>"<code>loose</code>"</dt>
* <dd>The HTML 4.01 Transitional document type.</dd>
* <dt>"<code>frameset</code>"</dt>
