18   *  The <code>CSSCharsetRule</code> interface represents a @charset rule in a 
19   * CSS style sheet. The value of the <code>encoding</code> attribute does 
20   * not affect the encoding of text data in the DOM objects; this encoding is 
21   * always UTF-16. After a stylesheet is loaded, the value of the 
22   * <code>encoding</code> attribute is the value found in the 
23   * <code>@charset</code> rule. If there was no <code>@charset</code> in the 
24   * original document, then no <code>CSSCharsetRule</code> is created. The 
25   * value of the <code>encoding</code> attribute may also be used as a hint 
26   * for the encoding used on serialization of the style sheet. 
27   * <p> The value of the @charset rule (and therefore of the 
28   * <code>CSSCharsetRule</code>) may not correspond to the encoding the 
29   * document actually came in; character encoding information e.g. in an HTTP 
30   * header, has priority (see CSS document representation) but this is not 
31   * reflected in the <code>CSSCharsetRule</code>. 
32   * <p>See also the <a HREF='http://www.w3.org/TR/2000/REC-DOM-Level-2-Style-20001113'>Document Object Model (DOM) Level 2 Style Specification</a>.
