Thinking about it again, just using semicolons does not help to solve the
problem at all. Often an object has multiple tags that belong together. If
you mash multiple objects together with semicolons, you quickly stumble over
your own feet expressing additional information.

In rural areas the village pub and hotel are often the same place, and the only

with public bars, both serving real ale. In this case one tagged as a pub and
one as a hotel.

Maybe not the best example, but one where it is often difficult to decide which
tag to use.
Often an amenity or shop will fit more than one category. For example a

Not really, because semicolons in amenity values lack a clear meaning.
Mappers try to express very different concepts with the semicolon
construct. For example, you may encounter an amenity=bank;atm, which

Hi!

I have used it, but I don't have a current example.
It's difficult because to do it right, you sometimes need to know if
a value is in the semi-colon value, and sometimes you want to know if
it matches exactly.
To that end, I ended up with somerthing like this (in pseudocode):
ele.tags = {
Similarly, I parse route_ref to identify which stops are served by a
particular bus route. Maperitive can't pick out the nodes from the relation
directly, so I was glad of the alternative/duplicate method.
