A couple of things ...
1. You might want to use RSS 2.0.
2. Fine to do html escaping for the "clean" <description> etc, but consider also offering
<content:encoded><![CDATA[
<p>Anything goes <em>here</em>.</p>
]]></content:encoded>
or
<body xmlns="http://www.w3.org/1999/xhtml">
<p>Anything goes <em>here</em>.</p>
</body>
Both methods would validate in http://feedvalidator.org
3. More info about RSS: http://slashdemocracy.org/links/Syndication/
