Chapter 10 - Type Inheritance Propagating Properties
Propagating Affects Types in the Sub-tree
When you propagate a property of a certain type, the property gets passed down
to the types in its sub-tree. For example, if you propagate the terminator of
Report, the terminator is assigned to all types in the sub-tree of Report.
When you propagate the terminator
of Report, the terminator is passed to all
other types in the sub-tree of Report.
