How much variation is acceptable within the standard.

What it is
A standard with no tolerance is either impossible to meet or is being enforced informally at some undeclared level.
Tolerance should reflect what the next step and the customer actually need, not what the process happens to achieve.
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.
