Ah, ok. So the base style defines a certain look for, say
"cycleway=lane", defining a "/lane" subpart, like:
way[cycleway=lane]/bikelane { casing-color: blue; ... }
A user could come along and say the bike lanes should be red...
way/bikelane { casing-color: red; }
That raises the question whether the syntax should distinguish between
defining a subpart, and merely referring to one.
Are there other use cases? It does still seem a bit of an uncommon case here.
