30  * Implementation of ModifiableDataController interface to manage data. It can

33  * may create transaction boundary.

39  * We need to generate interface since xdoclet will require them for interfaces
40  * derived from BasicDataController. Since remote and local interfaces have to
41  * extend different ejb interfaces and we have only one base interface, the
42  * extends tags have to except our controller contain also the interfaces
43  * required by the spec
