An enclosure basically marks what is being linked to as being "part
of" the document.

Thus, if you were to "save" the document, then you should save all the
enclosures too.

It's similar to an "attachment" you get with e-mails.

So for your example, if you considered that PDF to be "part of" the
HTML document... then it is correct.

Off the top of my head, both Fireant and Feedburner support rel-enclosure.

I've seen (and even written) Greasemonkey userscripts that support it.

And have written a webcrawler (and parser) that supports it.

(There's probably more... that's just what comes to mind right now.)
