The surfaces

Which written surfaces the voice covers.

The part

What it is

Error messages, form labels, invoices, out-of-office replies and support responses are read far more than campaigns and are governed by nobody.

Coverage should be listed explicitly, because the unlisted surfaces are the ones that drift.

The smallest level

The attributes it carries

Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
