[Tagging] Feature Proposal - crossing=marked

Yes, but a traffic light for whom? I've seen mappers who assume it means
"walk"/"do not walk" lights like this:

I've seen mappers who assume it means there is a sign *just* to warn
traffic about pedestrians, as can be found in the UK. I've seen mappers who
assume it means there is a nearby traffic light that means cars sometimes
stop at this location, but it doesn't say anything about having a
"walk"/"do not walk" sign.

The wiki only says, "Position this tag where the crossing-traffic
(pedestrian, bicycles) have their own traffic lights.". Pedestrians having
"their own" traffic lights would seem to imply the lights are specific to
the crossing and not that cross-traffic has to stop sometimes, but it does
not say which type of traffic light: cross-traffic (cars) or pedestrian
traffic. I've tended to assume it's the former, but have run into many,
many mappers who think it's the latter.

I tend to avoid mapping it at all because I don't want to add ambiguous
data to the map.
