Property :: dereference - Dereference collection handle

For collection properties, the function returns a dereferenced property handle, i.e. a property handle, which refers to a single instance rather than to a collection.

Dereferenced property handles cannot change selection.

The instance area is shared with the instance area of the original handle and the instance is associated with the collection of the original handle.

The function throws an exception, when the property handle is not valid.
