[Tagging] RFC - emergency=aed (defibrillator)

[Johan Jönsson]

I thought it would be a good thing to at öleast pass the proposal-phase for 
the tag emergency=aed

#The value aed seem to be the agreed value, it is a abbrevation of Automatic 
External Defibrillator (An AED is a device designed for the layman to treat 
life threatening cardiac arrhythmias).

#The key seem to have migrated from man_made to amenity to medical to 
emergency.
the contributors to the map prefers medical=aed according to taginfo.

llator

Anyhow, I seemed it fit to take this proposal up one more time, as the tagging 
pair emergency=aed never was sent out to RFC.
