[Tagging] Proposing additions to features

[Matthias Meißer]

Hi Paul, normally this is not a problem as long as you point out, that 
there are changes to an existing tag. When ju just extend it, it is very 
simple. More difficult is it when you change the functionality e.g. move 
highway=street_lampt to amenity=street_lamp. In this cases you have to 
be prepared to defend your ideas against a mass of contras by the 
community ;)

regards
Matthias
