[uf-discuss] Signalling use of microformats?

[Angus McIntyre]

Is there a way to indicate - for the benefit of robots, for example - 
that a given web page contains markup that conforms to one or more 
microformats? I'm imagining something along the lines of:

	<meta name="microformats" content="tag hAtom xFolk" />

Obviously, a robot would be free to scan any page to see if it 
contained content in a format it's interested in, but a 'hint' of 
this kind might allow the robot to prioritise processing of pages 
that the author claims contain information in a specific format.

Useful? Or superfluous?
