Just to clarify a few of Martin's points...

This should be (note the replacement of a ' ' with a '.'):

In an attempt to not create confusion - hset identifiers are only
relevant on the same page. If you had one page that contained an hset
named 'hset.foo.bar' and another page that contained an hset named
'hset.foo.baz' - per hSet there is no relationship that you could infer
from the similar names.
However, if both of those identifiers were retrieved from the same page
- you could infer a relationship between the two elements.

Martin, unless I interpreted Chris' problem solution proposal
incorrectly - his proposal does support sparse grouping.

So does hSet... the only difference is that in the case of hset may be
done out-of-order. Chris' proposal must be done in-order. For example,
this is valid in hset:
With Chris' proposal, the parser wouldn't be able to infer any
relationships until the entire page had been parsed. Although, that's
really not that big of a deal...

It really shouldn't - browsers and parsers should be able to handle
thousands of IDs per page.
Chris' proposal accomplishes the same things that option #3 accomplishes
- it solves the grouping problem. Really, I think this has turned into
a discussion on whether we go with Option #7 (Chris' proposal) or Option
#3. Arguments for going with Option #3 have been provided... input from
the community on which one to choose would be great.
