Yes.  See http://microformats.org/wiki/hcard-parsing , which is specific to
hcard, but is the place where I'm capturing a lot of microformats parsing
specifics to begin with (using a concrete example is usually the best way to
introduce more abstract concepts/algorithms).

Because "title" should *only* be used for microformat data on <abbr>
elements, and <abbr> elements should *only* be used when the "normal" (i.e.
default human readable) content in the element in unsuitable.

We want to minimize <abbr title=""> usage, because it makes the content a
little less visible.  The only reason we use it at all is to comply with the
human friendly principle while still making those values parsable for
machines.

Thanks,
