http://trac.tools.ietf.org/wg/websec/trac/ticket/17 refers to an IANA
registry with magic numbers for various media types. I wanted to
compare them to what's in the draft, but I couldn't find it. I found
the media type registry, e.g., for images:
http://www.iana.org/assignments/media-types/image/index.html
but I don't see any magic numbers. Would someone be willing to point
me in the right direction?
I don't think using a registry is a good idea. When a new MIME type comes
along it needs to be determined at that point whether or not we want to
sniff for it. E.g. for image/svg+xml, a new image MIME type, we decided we
would not sniff for it.
I suppose we could somehow encode all that information in a registry, but
I do not see it making things any better for implementors.
