[FLOW3-general] Extending a model

[Dawid Pacholczyk]

Hello List,
  I`m wondering on one thing

For example I have to simillar models

Person, Boss (lets not think about the best way of designing it but just 
on the problem :) )

Person and Boss can be grouped in People group OR Boss can EXTEND Person 
object

For example I would create a model Person with attributes: name, surname
And I would like to create a Boss object with attributes: name, surname, 
region

Both objects are simillar so normaly I would do something like this

class Boss extends Person {
	protected region;
}

That way I don`t need to copy attributes.

How should I manage this in FLOW3 ?

Best regards,
