I have an open bug on Web IDL to consider adding function types:

  http://www.w3.org/Bugs/Public/show_bug.cgi?id=12385

but in the meantime, how it is specified at the moment is fine.
[Callback] actually means that you could write either

  requestAnimationFrame(function(time) { ... });

or

  requestAnimationFrame({ sample: function(time) { ... } });

[Callback=FunctionOnly] disallows the latter form, if that’s what we’d
prefer.
