I read 'specialisation' and take away a semantic of 'a subset'?
An electrical engineer is a subset of all engineers?

Is this different to Erics request where he wants to identify an
additional property?
  Here is a person (or business) and they have a telephone.

Are these two 'different' from perspective and from a semantic view?
