I think that parsing this sort of tag set is very tricky because it
might overlap with other valid tags, for instance some building
addresses are 'The Water Works, 1-4 Testing Avenue' and I'm not sure
that interpolating the building numbers in this case would be correct.
 If you use the proposed:

addr:interpolation=odd/even/all

tag suggested in the subproposal it at least gives the parser some
hint that the building number should be handled in this special way.

Personally from the point of view of parsing simplicity I'd prefer two
nodes within the building polygon using the standard Karlsruhe Schema
- parsing it is difficult enough with out adding huge numbers of
exceptions!
