I have gone through some posts (if not all) that speak about "children
feature", I read the note in the GMF tutorial but I am still not
understanding completly.
They say it's for specify "where children are taken from". Sorry, but
children in a graphical meaning or semantic ? What does it mean taken from
(from where they are stored = containment)? It seems to be created to do a
derived association, am I right?
Adding on that that the use case they give as an example is very specific.
Does someone have a clear definition of "children feature" and how to use
it ?
