Nerds at Work

I was learning about Firefox extensions today, and I happened upon this. Look at the XML NameSpec URL:

<window class="dialog"

title="CovertProxy - About"

orient="vertical"

autostretch="always"

onload="sizeToContent()"

xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">

It took me a while to figure it out, but that's pretty clever, and REALLY nerdy.
