/**
* Tells that a metamodel property is derived, ie computed from the value of another property.
*
* For instance {@link CtType#getFields()} is derived from {@link CtType#getTypeMembers()}
*
* It can be put on getter and setters.
*
* Contracts:
* - A setter with @DerivedProperty only triggers one single model intercession event,
* on the element primarily responsible for handling the state from which this dervied property is computed.
* - A getter with @DerivedProperty is never called in CtScanner and derived classes (clone, replace)
