Oh, huh, I didn't realize we supported that.  We're buggier than you
let on, though - we appear to *only* support the <image> argument for
content on non-pseudos.

Do you know who depends on this?  We should fix this bug, even if it's
just by jumping ahead and switching to the 'replaced <image>' grammar.

Not in the near future.  It's on mine and fantasai's lists, but we're
both busy with other things right now and that's a pretty involved
spec.
