If content-type sniffing is context dependent -- @font-face sniffs font
types which img@src doesn't -- then the draft should be explicit about
that, rather than suggesting font sniffing for image sources.

There's no justification for allowing video@src or audio@src to be
sniffed. It just opens the door to more problems, and is not supported
by the justification of backward-compatibility with deployed content --
is there any other justification, besides someone "sort of expect"ing
it?
