There are cases in which the same RA provides connections of the different types. If the client application calls an additional getConnection method of the RA and provides the meta-info to it, which contains e.g. the java type of connection, and then casts the returned connection to the type it has requested ClassCastException occurs. Another example is JBoss' JMS RA; it provides a class called  org.jboss.resource.adapter.jms.JmsConnectionRequestInfo which implements of javax.resource.spi.ConnectionRequestInfo. org.jboss.resource.adapter.jms.JmsConnectionRequestInfo defines the type of connection returned by RA: topic, queue or both, I assume all of these types can not be put into the same pool.
BTW I thought that was one of the reasons for org.jboss.resource.connectionmanager.JBossManagedConnectionPool.PoolByCri implementation.
If you say:

why do you need any additional infrastructure for the re-authentication?
"vickyk" wrote : The -ds.xml should then supply the infrastructure needed to support the reauthentication i.e reauthentication mechanish as in case of jdbc rar. 

And if we use a JCA-compliant RA supporting re-authentication, who is responsible for supplying a re-authentication mechanism?
Even in case of JDBC no additional mechanism is not necessary in -ds.xml; this mechanism should be behind getConnection, as described in chap. 9.1.9 of JCA specification.
IMO the only what -ds.xml needs is:
"dimonv" wrote : Probably an addition tag within -ds.xml combined with "ByContainer..." is needed to give org.jboss.resource.connectionmanager.JBossManagedConnectionPool a hint which pool implementation should be used. 

Thus if -ds.xml says e.g. true and <security-domain-and-application>sec domain</security-domain-and-application> or <security-domain>sec domain</security-domain> then PoolBySubjectAndCri resp. PoolBySubject should be used.
