you need to store school terms in addition

I didn't come up with it, it's already being used for other similar things
where the same tag appears multiple times.

It's a limit so stating limited is redundant

Except that is putting values on the key side of things. To do things properly
you would need something like this.
maxspeed:school_zone=40

No matter what happens school holidays or the inverse can be mapped to some
administrative boundary.

I agree, but my point was there could be a combination of restrictions at the

be the trick to this,
