It already is valid, according to the formal specification, though none
of the examples use it, and it does look a bit odd until one realizes
what it means. (I had no trouble understanding it, but a lot of other
mappers still don't realize opening_hours and friends have a specific
syntax and aren't free form text fields where one can just slop anything.)
