For Express Schemata, dictionary models may not be deleted if data models (populations) of it exist in the database. Neither can it be deleted if it has been refereed to as a source schema or a target schema by any Express-X dictionary model. Therefore, all corresponding data models and Express-X dictionary models must be deleted before the Express Schema it self may be deleted.
