The operator set may not always be sufficient. The user should be allowed to define his own migrations whenever the operator set does not suffice. WebDSL would be the preferred language for writing migrations. These custom migrations may be stand-alone (no meta model changes), or overwrite a coupled operator (known meta model change, but a different migration).
