The description on persistable data objects in RHDM should be corrected.

The description on persistable data objects in RHDM document [1] may be misleading (give users a misunderstanding) as if we can persist such objects for rule use cases, though persistence feature is actually not supported in RHDM (for rule use cases). So as to avoid such misleading, the description [1] should be corrected appropriately, e.g. add note that persistence feature is not supported for rule use cases, or remove the description of the step 4 (to make a data object persistable).

4. To make your data object persistable, select the Persistable checkbox. Persistable data objects are able to be stored in a database according to the JPA specification. The default JPA is Hibernate.
