Linking to alternate resources

Not directly connected to the "confusing" part of the linking mechanism, 
but re-reading today's minutes:

The mechanism being exactly the same as the one used to link to a CSS 
style sheet, user-agent cannot be used for linking to alternate 
representations, but CSS media queries should still be part of the 
equation with the possibility to define something like:
	media="handheld and (max-device-width: 200px)"

I don't think anyone uses links to alternate representations with that 
level of details for the time being though (and CSS media queries is a 
Candidate Rec, not a Rec)
