Hi Jeff,

I am not quite sure how deeply you thought about your argument.
Layering the language does not introduce any new documents.
Instead it helps to break a long and thick document into a number
of significant smaller ones. Therefore, most readers have to read
less and not more material. They (tool and application builders)
can refer to a smaller piece of technology they want to support and
they need. By giving this strata a name you have a defined way
in which people can realize the level of complexity they need.
Without such strata you have one bad alternative:

-       people are forced to subscribe to an over-complex approach
         for their goals, or
-       people introduce ad-hoc subsets without any clear linkage
         to other ad-hoc subsets.

As I argue for such a point of view now for more than three years
without having heart any convincing counter-argument I am not
going to add one more word on it.
