I suggest you do.

Duh.. one is derived from the other.  In fact one is a definition of
the meaning of the other one.

Whether your converter's rule says
canvec:type=X -> amenity=school
canvec:type=Y-> tourism=hotel, rating=3 stars
or they're both amenities doesn't really make a difference, does it.
It's still a clear correspondence between tagsets.

If you had read the message to which you were responding though you
would notice I'm not suggesting the canvec tag be removed, from which
the osm tag was derived, just the second canvec tag that contains a
textual, english language definition of the first tag.  On *every*
object that uses the tag, the exact same two-three english sentences
(see the prime numbers example)

Cheers
