I was using the syntax: word, followed by a colon, followed by an
extended identifier (at least [Unicode] alphanumerics, underscore,
hyphen, and maybe a couple more punctuation characters, such as colon
and period).  I think that syntax should be locale-agnostic, as long as
we require left-to-right interpretation.

I chose 'lang' and 'bin' because they are common technical abbreviations
-- 'lang' is the official attribute for content language in several
markup systems, and 'bin' has a precise meaning on many OSen and is
easier to type than 'executable' which is what I really mean.  However,
I am not wedded to the existing names; if there's a strong consensus on
this, I'll probably follow it.

I'm not clear what this namespace would be used for.  Is it for
specifying a VM that must be available?  Like 'runtime:hotspot' or
'runtime:v8'?

As a side note, it's implicit that anything installed by Plumage
requires Parrot -- because Plumage itself requires Parrot to even
run!  :-)
