Multiple values for a tag is certainly useful and needs to be
supported, IMHO.  But, that doesn't necessarily mean that the API
needs to support duplicate keys.  Delimited strings are fine as long
as $EDITOR hides them from you.

Nevertheless, I think duplicate keys are the cleaner solution.  If it
really hurts database performance or if there are other technical
reasons why way/key pairs must be unique in the database the API could
concatenate the values and split them on data delivery.  But, I am
sure this has been discussed before, so forgive me.
