Of course, i was just trying to point out that the standard OSM map does 
not really give a good example here for others to imitate.  Since the 
style is open you can of course see where external data is used but 
this only works as long as it is open.  Anyone who uses a proprietary 
style but otherwise follows OSMs own example in terms of attribution 
will not have this information available including those styles on 
osm.org which are not open.

And the ODbL as far as i can see does not make any difference if a 
derivative/collective database contains data originally published under 
an ODbL compatible license or not.
