We've been wracking our collective brains on how to make what your
proposed to work, but keep having the same sorts of problems. If we
didn't have to deal with sparse groups, your solution would be perfect.

In a way, this is a perfect example of why we need to collect examples
for any Microformat - if we weren't collecting examples, we would have
probably adopted something very similar to what you proposed (and not
addressing the real problem in the end).

I don't think we should expand it to a design pattern until we see it
used in several other Microformats. Let's keep it semi-constrained for
right now because it doesn't cost us anything to do so.

In addition, several Microformats will need to use hset to identify it
as a design pattern. You are correct - it is a VERY simple Microformat
and probably will become a design pattern eventually.

Let's let hset take its natural course and not rush it into being a
design pattern before we are sure it will be used as such.

Then if there are no objections - I'll write up an hset proposal and
submit it to the list for feedback in the next week or two. We'll do one
more round of feedback for haudio and hset after that and see where we
