As I posted earlier today, I favor this idea, but I dislike this
syntax.  Because of the #*$# interoperability restriction, we
should avoid using "True" and "False" for any attribute values.
Also, boolean attributes in general often indicate a poorly
thought out design (See _Writing Solid Code_).  Just what is "true"
or "false" anyway?  That it must be a root? No.  That it can be a root?
No (anything can be a root).  That it should be a root? No.  "False"
ends up meaning "It shouldn't be a root", but "true" has no specific meaning.

I propose:  Root (Useful | NotUseful) "NotUseful".
