[whatwg] <img> element comments

[WeBMartians]

Clarification- "never explicitly defined" should probably be "never explicitly 'limited'"
	The W3C documents seem to require support for, at least, GIF, JPEG, MNG and PNG.
	Apologies if this is just nit-picking.
		[I'll regret saying this, but I wonder if the list can be pruned with the expiration of the GIF patents.]

I think you're putting too much emphasis on the words "for an image" in what I wrote.  I think my intention was to avoid cases where it's pointing to itself.  In practical terms, it just needs to point to file in a format that browsers support for <img>, but HTML has never explicitly defined which image formats browsers should or should not support, and I don't think it should.
