The program DEMO_CDS_CUSTOM_ENTITY_ELEM shows that the element annotations of the CDS custom entity can be evaluated using the class CL_DD_DDL_ANNOTATION_SERVICE. The result set contains not only the direct element annotations, but also derived annotations which are defined for the data element used for typing.
