What he said:

=====
I also think tools can deal with semicolon-delimited lists just by
internally converting:

key=value1;value2

to a temporary array:

key[1]=value1
key[2]=value2
=====

So the data in OSM is still "color=purple;orange;green" but
represented to the end user as a color[] array.

If the client implements a semicolon to array converter then probably
it will also have some way to query it without using a regex
(something like python's "in")
