I would like to see that possibility extended to RDFa, too. The simplest approach would be to allow <link> and <meta> in the body in general. The RDFa processing model would handle those out of the box.

Ah, so it has already been filed. Great.

Correct. Right now it is not advisable to use them for the reason you cite below. But if HTML5 adopts this then, eventually, this may become a good, actually probably optimal way of doing this.

(This might be a problem for server-side parsers as well, I guess; I don't know whether off-the-shelf HTML5 parsers have the same problem.)
