to this object.scope
- specifies the scope.composite
- indicates the composite type.
It can be one of "none", "list" or "map".
If null or empty, "none" is assumed.java.lang.IllegalArgumentException

Notice that, prior to 5.0.8, "component" is returned if it is not associated with a scope (which is not correct since this info might be associated with a page).
