HTML 5 tags and audio stripping

For a variety of reasons, we'd like to have HTML5 audio tags in an Omeka item and not use the HTML Five plug-in. I'd like to use the code:
<p><audio controls>

<source src="http://xxx.mp3" type="audio/mpeg">
Your browser does not support the audio element.
</audio> </p>

I have the following lines in the HTML security settings but Omeka still filters the tags out:


Any explanations or suggestions?

This is tricky.

The HTML filtering component we use isn't updated for HTML5. At a minimum, I think you'd have to disable the filtering to use new HTML5 elements directly like that.
