The overlaps
Segments more than one route serves.
The part
What it is
These are where conflict will occur, and identifying them in advance is what makes the conflict rule specific rather than general.
Some overlaps are deliberate and workable when the rule is clear; all overlaps are damaging when it is not.
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.
