Please add a method getName that takes an element, and returns 'default' if the
name is empty. And use that method here and in instanceName.

Done.

[floitsch, 2011/12/08 16:36:00]

Actually it must be a constructor. This is necessary, as we need to get to the
body-constructor from a constructor when we call 'super'.
Added comment and assert.
