it appears to me that before discussing possible solutions we should
better agree on what the problem is. So far I see several related but
different problems mixed into one and consequently no possible agreement
on the solution.

The problems I have picked up from the discussion:
a) as a data consumer I want to know the language(s) for a given name tag
b) as a data consumer and as a mapper I want to know which language(s)
   is/are commonly spoken in a place
c) as a data consumer and as a mapper I want to know which language(s)
   is/are ususally used on name signs in a place
d) If there are names in multiple languages combined to form the name
   tag in case a, I want to know how to split a given value into the
   component languages.
e) If names in multiple languages are used together in case c, I want to
   know how to construct the name tag from the component name:xx values.
f... all the points I have missed/forgotten/ignored/...
