  <descr>
    <p>
      The <code>CSSCharsetRule</code> interface represents a <xspecref
      href="&css2;/syndata.html#x66">@charset
      rule</xspecref> in a CSS style sheet. The value of the
      <code>encoding</code> attribute does not affect the encoding of
      text data in the DOM objects; this encoding is always UTF-16. After a
      stylesheet is loaded, the value of the <code>encoding</code> attribute is
      the value found in the <code>@charset</code> rule. If there was no
      <code>@charset</code> in the original document, then no
      <code>CSSCharsetRule</code> is created.  The value of the
      <code>encoding</code> attribute may also be used as a hint for the
      encoding used on serialization of the style sheet.
    </p>
    <p>
      The value of the <xspecref href="&css2;/syndata.html#x66">@charset
      rule</xspecref> (and therefore of the <code>CSSCharsetRule</code>) may
      not correspond to the encoding the document actually came in; character
      encoding information e.g. in an HTTP header, has priority (see <xspecref
      href="&css2;/syndata.html#x66">CSS document representation</xspecref>) but this is
      not reflected in the <code>CSSCharsetRule</code>.
