Well, in a way you're right in that what HTML uses does go inside the
start tag for the "a" element - it's the rel and rev attributes, not the
content of the link.

But in neither case does HTML distinguish between referring to Liam
Quin, or to Liam Quin's home page, or to a picture of Liam Quin, in a
machine-readable way.
