I think that 4-way and 3-way stops can be handled unambiguously by
highway=stop.  More complex stops should probably be modeled with turn
restrictions.

type=restriction
restriction=stop
roles=from,to,via

A 4-way intersection where 2 opposites stop, A & B, and one continues,
C&/or D, through, E, can be modeled with a single relation.

Eg:
from:A
from:B
to:C
to:D
via:E

3-ways with a single stop can be done similarly.

Cheers,

Adam
