Thomas Russ has suggested the exact same thing (to Brigitte) but with a different name, i.e. "creating a prototypical individual for each topic class". And I take that you also prefer this way over the 'meta-modelling' approach, which involves using puns.

I am writing this quickly but I think that there is a working group 
document [1] about this very issue [2] .  I think the reference 
individual approach is approach #2 and my favored approach is closer to 
approach #4.  Given the authority of this document I would figure that 
these are all valid approaches.

> 2) Is there an established name for this design phenomenon? I am just asking because if there is one, I would like to stop calling it "reference individuals" and start using the appropriate jargon and use it as my key-word/phrase to 'google' and read more about it.

I don't know - approach #2 and approach #4 is worse :).
