For the Ordnance Survey, there is a small amount of cooperation from OSM in the
form of a list of street name errors which they have agreed to look at.  Since
this is just a list of possible mistakes, it is generally held that this does not
breach copyright.  It is an interesting question whether this could continue
under the proposed ODbL or whether it would technically be in breach of the
contract-law provisions.
