I'm not suggesting XML-like parsable namespaces, of course, just a
recommended naming scheme to reduce conflicts later.

Non-prefixed names could still be supported if that happens, if the de
facto usage is consistent enough to do that.

Instead of "namespacing", maybe it's better phrased as "all names beginning
with VTT are reserved".  That way, it doesn't imply that we'll never
support anything *not* beginning with VTT, if it makes sense down the road.
