The date

When the vision is expected to be reached.

The part

What it is

A year rather than a decade-in-general. “By 2035” produces different behaviour from “in the long term”, which produces none.

The date is a commitment about attention rather than a forecast, and saying so removes most of the resistance to setting one.

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.
