HTML Report - Capabilities

I think this is what is used to render the HTML reports - research ongoing though: oracle.adf.view.rich.component.rich.output.RichOutputFormatted

This indicates support for the following tags:

<br>
<hr>
<li>, <ol>, <ul>
<p>
<b>
<i>
<tt>
<big>
<small>
<pre>
<span>
<a>

Capabilities I have confirmed so far:

TABLE
Inline CSS via the STYLE attribute

Capabilities I can't get to work so far:

<style type="text/css">
