The guidelines
Which standard is adopted.
The part
What it is
The Web Content Accessibility Guidelines are the practical default, and the version matters since the criteria differ.
For non-web interfaces the equivalent standard should be named rather than assumed.
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.
