This is my interpretation of auto-discovery, too.

However, there is not consensus on this point:

Ah.  Then the question doesn't make sense as defined, since  
microformats are
used *in* the content, not somewhere else where a rel="alternate" link
points to.

Tantek seems to be saying that since microformats are embedded, then  
you can't auto-discover them like you can with RSS.

However, UAs that notify users of possible actions based on the  
microformats seems to be the right thing to do. If we don't call that  
auto-discovery, what other terms fit better? Auto-notification, perhaps?

This sounds like using the index page as an index to all content,  
which feels like the way things are headed. However, if there is no  
explicit link to the content, publishers can't ever change where they  
publish their hCalendar, or there needs to be some sort of  
notification system in place in the case they do.

Not everyone will want to have their calendar information on their  
home page. From what I've gathered from folks on this list, one of  
the strengths of microformats is that they can be embedded on any page.
