The idea that of all the tags an object has, one should be "primary" or 
"character giving" is something that many people come up when they try 
to sort through the chaos that is OSM tagging.

It mostly works - most objects indeed have one defining tag.

But there's no rule that it always must be so; your example of something 
being a highway=tertiary and a railway=tram at the same time is 
perfectly valid; or something could be an abandoned railway and a 
cycleway at the same time.

I think it is a legitimate design decision for an editor to not allow 
its users to create such objects, as long as care is taken that the 
editor does not silently alter the definitions of such objects that 
already exist.

Bye
Frederik
