I don't see any guarantee here. Author of any library can write down
sentence stating "This is applicable spec for my FOO library. This
applicable spec extends HTML5 by attributes prefixed foo-.". Then
nothing will prevent him using foo-, it will be within bounds of the
current HTML5 and possible clashes will not be prevented.

After all possible clashes to my knowledge can be prevented in two ways
-- either by having central registry for prefixes or by using some
indirect mechanism like namespaces.

So insisting on using data-* for libraries is little bit hypocritical --
it just requires typing additional 5 characters and doesn't bring any
real advantage.

In my opinion we should either allow prefixed attributes and require
prefixes to be registered in some sort of Wiki or introduce something
like XML namespaces in HTML syntax.
