After removing most of the Semi-colon value separator
<http://wiki.openstreetmap.org/wiki/Semicolon> article then (and stating
that "Most OSM Tools, map renderers, taginfo and the XAPI *do not
handle* these values" is tagging for the renderer :-) ).

I also would feel like accepting the semicolon, but after thinking twice
I notice that
religion=religion1;religion2;....;religion
denomination=denomination1;denomination2
would become even more problematic already.

And after thinking many times, I always come back to the idea that we
should not code
shop=this;that;...  but sort of  this=shop  that=shop
nor highway=crossing + crossing=*  that makes a funny type of a highway
but simply crossing=* that allows it to also be longitudinal to any way
nor historical=castle but something like   building=yes  castle=yes
built=1850 (i.e. historical=no) [defensive=no] hotel=yes
wine_producer=yes ...
nor...

And so, discovering the following in the above article came as a
surprise to me:

> amenity=library
> library:stock:books=yes
> library:stock:newspapers=yes
> library:stock:recorded_music=yes

because it's much like your problem and my repeated thinking, except
that library=yes should follow the same principle in case some other
activity takes place in the same building=yes rooms.

Your problem is like a shop that sells many kinds of goods, a building
that serves many purposes, a water that can be of many types, a crossing
that's in fact a passage across or along any way, a dam that is not a
circular waterway, etc...  I think they all have the same generic solution.

Cheers,

André.
