268	<p>Since the <abbr title="Cascading Style Sheets">CSS</abbr> 2.1
269	specification is sometimes ambigious or disagree with browsers,
270	our implementation is tend to copy what browsers do unless
271	there is strong resaon to do different thing.</p>
272
273	<p>In addition, the current implementation assumes that there are following
274	requirements:</p>
275	<ul>
276	<li id=css-type-charset-param>The <code>charset</code> parameter of the media
277	type <code>text/css</code> <em class=rfc2119>MUST</em> be treated as if it

279	an <abbr>HTML</abbr> <code>style</code> element.</li>
280	<li id=css-style-content>Content of an <abbr>HTML</abbr> <code>style</code>
281	element whose content is interpreted as a CSS style sheet
