   If your entity is modelled with the [composition of aspects](../../cds/cdl#with-named-targets), the generated interfaces always reference original aspect as type for setters and getters.
   When this switch is enabled, the code generator uses the type generated by the compiler instead of the type of the aspect itself and will include methods to fetch keys, for example.

   CDS models from external sources might include elements that have some special characters in their names or include elements that clash with Java keywords. Such cases always can be solved with the [renaming features](../cds-data#renaming-elements-in-java) provided by code generator, but in case of large models, this is tedious.
   When this switch is enabled, characters `/` and `$` behave as a separators for the name during case conversions, similar to `_` and `.`. For example, `GET_MATERIAL` yields `GetMaterial` (or `getMaterial` for attributes and methods). The same now applies for the names with `/`, for example, name `/DMO/GET_MATERIAL` will be converted to `DmoGetMaterial`.

   The method `getService()` in generated [event-specific Event Context interfaces](../event-handlers/#eventcontext) is overridden to return the typed service interface instead of the generic `Service` type.

   This significantly improves performance and removes the limit on the number of methods an accessor interface may declare.
