I disagree. The semi-colon delimiter should be used. I doubt people could 
remember which rule to apply, and I don't agree it should be applied 
anyway, as for any particular roadway, the name by which it is colloquially 
known is inconsistent. CA example:

I-215 shares routing with SR-60 for a few miles. People in the area still 
consider it SR-60. It is tagged ref="CA 60;I 215".

SR-79 shares routing with I-15 for a few miles. People in the area still 
consider it I-15. It is tagged ref="I 15;CA 79".

These actually conform with the second rule above (and the third, but 
that's entirely coincidental), but I'm sure I can find counter-examples.
