[Tagging] Estimated Housenumber interpolation

I believe there are many uses for an extension of the address interpolation
concept to data and surveys of less than 100% accuracy.
- Survey of streets of new construction where the endpoints are known, but
not all houses are yet present.
- Survey of streets of new construction where the endpoints are not known,
but a possible range can be estimated.
- Use of US TIGER data to indicate all possible addresses on a block;
useful for routing to the nearest block where no survey has been done.
- Survey of established communities where house numbers are missing or
damaged beyond recognition. This is often coupled with irregular numbering
in which it isn't known if a house lot size = 1 or lot size = 2 (takes one
numbering slot or two). Since a survey was done, the house could still be
accurately Geo-located without the mapper knowing the actual number.
The question is how to tag these. I've seen something like
addr:inclusion=actual -> Exact survey; the traditional meaning of the
Karlsruhe Numbering Schema
addr:inclusion=estimate -> The address interpolation way may contain
numbers that don't actually physically exist. A survey has been performed,
and Geo-location would be very close.
addr:inclusion=potential -> The complete range of all possible address
numbers on a block, although there may not physically be enough room on the
block for that range of house numbers. From US TIGER for example.
Geo-location would only be as near as one block.
There are more accurate English terms, but they are very verbose.
Any other ideas.
