You can safely embed any external HTML code on your pages. To guarantee maximum safety, HTML code is placed in a safe environment (iframe sandbox) to limit the possibility of cross-site scripting attacks.

E.g. to display del.icio.us tag cloud as generated from http://del.icio.us/help/tagrolls simply wrap the html code in a [[html]]…[[/html]] tags:

[[html]]
<script type="text/javascript" src="http://del.icio.us/feeds/js/tags/michal_frackowiak?icon;size=12-35;color=87ceeb-0000ff;title=my%20del.icio.us%20tags"></script>
[[/html]]

Note: previously [[html]] tag functionality was partly covered by the [[embed]] tag, which is now deprecated and aliased to [[html]]. This is why you might still find [[embed]] tag here and there.
