We need to be able to map partially enclosed courtyards as well, e.g.:
(The courtyards are named Hof 1 ... Hof 7.)
But I agree that a courtyard *typically* is fully enclosed by buildings,
thus not an emergency feature. There's an approved tag entrance=emergency
for emergency exits, and I'd suggest a tag like emergency=access for spots
and alleys designed to be accessible for fire fighters.
I think that, from a technical point view, the main function of a courtyard
is to yield sunlight to building rooms that are not adjacent to the
building's outer margin. All other uses, such as recreation, parking or
emergency access, are subsequent.
