+1, if we find something more useful than the current proposal we
should ad it as a contrubution to the wiki (maybe on another page but
linked from the above proposal)

yes, this is no longer supported in api 0.6

+1, I can't really see the point of not putting values in keys
actually. Aren't we already doing this in many tags?

why is this a value in the key:
maxspeed:wet=40
couldn't you interpret "maxspeed:wet" as a key? The maxspeed in wet
condition? Could you explain the problem that arises (I am not an
informatics person and maybe for this don't understand these details
adhoc).
