That's clever. Added it to <http://santek.no-ip.org/~st/tests/picturetag/#tb>

Note that Safari (2.0.4(419.3)) doesn't present any fallback in this case. A
bug, I presume?

Well, your suggestion at least does allow authors to provide users of modern
browsers with a better experience.

Still, I think both conditional comment approaches are too hard for authors.
Especially if we mean to entice them to use <picture> instead of <img>.
Robert Burns' approach is the only one that seems reasonable to me to expect
from authors. Provided no <param> is needed, the spec's object definition
becomes author-friendly, and IE is fixed. {Ahem} :)
