A large fraction of 'authorative' sources of boundary data have very 
little to do with the legal/contractual definition of the boundary.  I 
would probably go as far as saying the most inaccurate boundaries in 
OSM come from authorative sources.

Not in OSM - see the 'on the ground rule'.  For OSM the boundary is what 
locals treat as the boundary.
