	It can be either "URL hex escaped" (don't know the formal term
for that 8-) or BASE64 encoded (same as for Basic Authentication) so lots
of Web software already has the functions for doing it, and it's just a
matter of adding an explicit interface.  Plus any hacker could whip up
a script for that in a matter of minutes, and offer it to the Web.

	This is another reason why it's so sad that the HTML 3.0 SRC
attributes were allow to be trashed, e.g.,

	<HR SRC="data:image/gif;base64,[custom horizontal rule]">

	SRC also should be added to STYLE:
	<STYLE SRC="data:..."></STYLE>
so that too becomes "backward compatible" for all clients since the
birth of the Web (as a content-rich, platform-independent, INFORMATION
sharing system 8-).
