I guess this issue is meant for MyFaces, not comdev?

> The HTML specification disallows certain code points from appearing in HTML files (XML has essentially the same list, minus the high ISO characters) as specified in http://www.w3.org/TR/REC-html40/sgml/sgmldecl.html.  The Trinidad HtmlEscapes utilities allow the low control characters and the high characters that are technically outside of Unicode to be output.  This causes problems if the content is validated.
> The fix is to use numeric character references such as &#1; rather than outputting code point 1 directly.  In addition, Internet Explorer has a bug where &#0; is output as "&#0;" so it is preferable to suppress this character rather then outputting it.
