IETF specs rarely govern local behaviours; their target,
if not their exclusive domain, is agreements *between* hosts
on the internet.

So when you send a URI over the wire (e.g. in an HTML
document) you're bound by the URI spec. But not, necessarily,
when you fidget with them locally.

By analogy, when I type
	% ping www12

there are local conventions that turn that into
before doing a DNS lookup.
