Message-driven bean's transaction attributes

HFEJB says:
Message-driven beans can use only TWO attributes: Requires and NotSupportd

My question is:
If it is possible to use NotSupportd then why can not it use Supports attribute.
Any way it�s going to run with an �unspecified transaction context�

Please clarify this�

MDB doesn't have any clients, so it is not possible for a MDB to run in an caller's tranction context.Transaction attribute 'supports' says that either a bean can run in caller's transaction or unspecified transaction context.Hence declaring the 'supports' transaction attribute for MDB doesn't make any sense.

parthiban ,
If MDBS have tranx attribute of "Supports" where do u think the callers transactional context will be delegated as the mdbs get triggered by the arrival of a message on its waiting queue and hence the attribute is no meaningful .
