EPP mux envelope

mux.xml

<?xml version="1.0"?>
<mux xmlns="foo">
	(<src>...</src>|<dest>...</dest>)
	<p>
		<epp xmlns="...">
		    ...
		</epp>
	</p>
</mux>

Me noodling how to multiplex EPP requests over a single connection in a way that doesn't cause a layering violation (Unlike the Verisign Namestore extension). It's not specific to EPP though.

The idea is that a client sends a request with <dest/> set to the destination server's ID, and the actual EPP XML document is put in the </p> (payload) element. In the response, the server includes the source server's ID in the <src/> element so the client can tell where it came from and so demux it.

This could be expanded with a status element, and possibly some kind of a service menu response (not dissimilar to the EPP greeting), keep-alive request, and an optional authentication mechanism. I'm not sure how useful an authentication mechanism would be, though.
