I am not really familiar with the legal status of aboriginal lands in 
various parts of the world and how use of the names differs betweeen 
the inside and the outside.  I have a hard time imagining an aboriginal 
land with a distinct and homogeneous language use that is not also an 
administrative unit.

If we could discuss this on a practical (and hopefully somewhat 
representative) example that would probably help.

I am not sure what exactly this tag is supposed to mean.  Is it just the 
format string i suggested indicating the locally preferred form of name 
display minus the actual form, i.e. reduced to a list of component 
names or is it something different?

And how is the data user supposed to interpret this tag?  Since you do 
not want to deprecate the name tag it is not clear to me if it is 
supposed to be interpreted in combination with the plain, possibly 
compund name tag or with the individual language name tags.
