multi data sources

</div>
<p>
We have already seen two single sources where CSS data could come from.
The last one allow to parse data from multiple sources at once.
<code class="methodname">HTML_CSS::parseData()</code> function take an
array as first argument. Each item is either a filename (with .css
extension) or a string. Each source is merge to produce at end a unique
style sheet.
</p>
<p>
In script below we load selector definitions from two independent
sources: a string and a css file which contents duplicate definitions
(parseFile() 2nd argument to set to true to catch this situation; see
next section for explains). Internet Explorer).
