All tags using defaults should not use their own, different but the same 
mechanism defined by the Defaults 
<https://wiki.openstreetmap.org/wiki/Tag:type%3Ddefaults>proposition.
Hence, a default for a tag
language=xxx
which can be coded in any OSM object is
def:language=xxx
coded in the administrative relation you say, or equivalent.

This allows uniformly writing/upgrading the same program to handle all 
defaults instead of each default using its own program.
The Defaults 
<https://wiki.openstreetmap.org/wiki/Tag:type%3Ddefaults>proposition 
must obviously be decided before the defaults that use it.

All the best,

André.
