Referential constraints are (hopefully) correctly enforced by the 0.6 
api - it wasn't possible before due to a lack of transactions.

Some (but not all) referential constraints are enforced in the database 
now. The particular issue addressed here is not enforced in that way as 
I am not aware of a sane way to do so with our current schema.

Data created before the transition may therefore violate some 
constraints in ways that the 0.6 api would not allow.

If you find recently created ways that reference deleted nodes then 
please let us know. If you find old ways that do it then just upload a 
new version and that will fix the data.
