You can enforce non-divergence between a domain and the columns/entity attributes that use the domain.
If you subsequently modify in your domain any of the properties specified as non-divergent here, then the corresponding properties of the columns/entity attributes attached to that domain are automatically updated.
Column/entity attribute properties specified as non-divergent appear dimmed and are non-editable in the List of Columns/Entity attributes and Column/Entity attribute property sheets. If you want to modify a non-divergent column/entity attribute property, you must detach the column/entity attribute from its domain.
