Specifies information about the resource adapter. The information includes fully-qualified names of class/interfaces required as part of the connector architecture specified contracts, level of transaction support provided, configurable properties for ManagedConnectionFactory instances, one or more authentication mechanisms supported and additional
required security permissions.

If there is no authentication-mechanism specified as part of
resource adapter element then the resource adapter does not
support any standard security authentication mechanisms as part
of security contract. The application server ignores the security
part of the system contracts in this case.
