The values for the parent objects are significant to the user and need to be
at least displayed if the user is editing a lower level. In my example
attributes from Level 1 are shared across a bunch of actual business
entities. Attributes from Level 2 are shared across one of Level 1's child
objects. When editing Level 3, the user doesn't get the whole picture unless
he can see (and preferrably edit) all the levels at once. But the number of
levels and the number of attributes per level can vary, depending on your
starting point (the type of business entity object you are editing).
If I understand your suggestion, the user would only be able to see/edit the
attributes for a particular level.

Thanks for your suggestion.
