semantic XHTML (OR semantic HTML)
This is well-used well-adopted pre-existing term and there is no need to
invent a new term to mean the same thing.

I'm frankly not ok with this.
This is one of the reasons why I have avoided capitalizing the term
"microformats" everywhere it is used. There is no "capital" variant. There
is just "microformats", as has been defined.
And just as "squares" are "quadrilaterals" with additional constraints,
microformats are semantic (X)HTML with additional constraints.
In particular, the difference between the specific semantic XHTML technique
"using semantic class names, ids, rel/rev values"
Is that *anyone* can make up semantic class names, id, rel/rev values, for
any reason in any way, and in fact, modern web designers and information
architects were doing so *long* before microformats was even coined as a
term. Indeed, it was precisely this pre-existing behavior that inspired me
to first even dare to propose microformats as a refinement thereof.
A "microformat" is such because it is a use of semantic class names, etc.
that IN PARTICULAR:
1. Are designed according to microformat principles 
2. Follow the microformats process 
Without those, all you have is semantic XHTML.
I have on my to-do list to better document the principles, more thoroughly,
etc., as well as update the process per what we have learned the past six
months or so. Perhaps this holiday season I will have to spend some time
catching up on this given the extent of this thread.
I will note that for now, much deeper explanations of the principles are
actually presented in the numerous podcasts about microformats that have
I encourage everyone who has participated in this thread to listen to them.
