Description
supported interceptors:
- global interceptors
such global interceptors are invoked before and after validation (in any case)
internally it should be used e.g. for custom group extraction add-ons
they are registered globally via the ExtValContext
- local interceptors
such local interceptors are invoked before and after validation (in any case)
they allow fine grained interception for every extval-constraint
they use the same interface as the global interceptors. but they are registered at a single constraint via the mechanism ofEXTVAL-43
