David, I was under the same false assumption. Microformats are
scope-less. There is no such thing as scope and binding... the only
thing that matters is the order that the Microformat elements are listed
on the page.

Here's some markup to demonstrate:

haudio
* hreview
** reviewer
*** vcard
**** fn  <---- the reviewer's name is used as the title for haudio
* fn <---- this is ignored by any Microformat-compliant parser

The parser would perform the following steps:

1. haudio detected
2. find elements for haudio
3. find name of audio recording (search for 'fn')
4. 'fn' found in haudio/hreview/reviewer/vcard/fn *OOPS!*
5. hreview detected
6. find elements for hreview
6. reviewer detected
7. find name of reviewer in vcard (search for 'fn')
8. reviewer's name found in vcard/fn
9. superfluous 'fn' detected, ignore 'fn'. *OOPS!*
