In general a tile layer is going to be rendered from a collective 
database, of which part of is a derivative database licensed under the 
ODbL. They're obliged to disclose the derivative database, but not which 
parts of it are used, and nothing about the other databases in the 
collective database.

The style documentation does cover other sources. Also, the other 
sources are all under ODbL compatible licenses anyways, so the situation 
is a bit different as the entire set of sources can be released under 
the ODbL.
