key:subkey=* is only usable (or even recomended) for standardized
subkeys. If instead you have a random value (like a road reference or
a street name), another scheme is necessary: key_<number>=*.

This has been debated (yet again) on this list not long ago for the
"name" key. The usual arguments followed. There are enough proponents
of both styles (each with good arguments) that both styles are clearly
here to stay (unless maybe the code data model gets updated to support
multi-value tags).
