Actually, I'm thinking this is a very common design pattern
(nanoformat ?). I can think of a whole bunch of cases where I'd
like to be able to specify a list of items, one of which is preferred:
* email addresses
* multi-res media downloads
* formats (HTML vs. PDF)
I think the most common HTML implementation of this is an ordered
list, where the first choice is preferred, i.e.:
<li>I am the greatest</li> <-- Default, aka Canonical -->
Of course, that's only useful is there's additional attributes that
allow for meaningful 'picks', e.g., size, language, etc.
Is there in fact a general way to handle this? Are these *always*
links, so we can use 'rel'?
