Poor Indiana. ;-) The definition of the foot would apply to the ' and ft 
abbreviations in every context, not just the ele=* key, so I'd suggest 
considering it separately, probably without the formality of a vote. The 
main unit symbol listing has come together more informally over the 
years. [1]

Sooner or later, OpenHistoricalMap will have a lot of fun with this issue...
