It's worth noting that when two objects are merged in iD it splits the 
tag's value into lists at semicolons, merges the lists from the two objects,

and then turns the resulting list into a semicolon separated list. See 
https://github.com/systemed/iD/issues/943. I believe iD is actually the 
only editor that attempts to support semicolon lists in tags. JOSM and 
P2 emit them, but don't interpret them.

This of course doesn't avoid contradictory tags like tiger:separated=yes;no 
but it at least avoids tiger:separated=yes;no;no;no;yes;no;yes;...
