Hmm, but both comments so far don't really say whether it's in-line
with current thinking on XFN to allow for XFN linking to non-URLs.
Given what you're saying, John, I should be able to also construct XFN
links like this:
<a href="aim:goim?screenname=factoryjoe" rel="me">IM Me</a>
And as such, do the same for email addresses... right?
This issue is fairly orthogonal to hcards, since you can have hcards
without XFN. To date, my interpretation is that XFN links to resources
not on the same page. It's not clear, in my thinking, whether those
external resources can take the form of URLs, callto: or IM links.
