/**
 * This class defines an interactive transaction specification response control,
 * which will be included in the server's response to an operation that included
 * the {@link InteractiveTransactionSpecificationRequestControl}.
 * 
*
* NOTE: This class is part of the Commercial Edition of the UnboundID * LDAP SDK for Java. It is not available for use in applications that * include only the Standard Edition of the LDAP SDK, and is not supported for * use in conjunction with non-UnboundID products. *
*
* It provides information about the state of the transaction, which may * include: *
    *
  • transactionValid -- Indicates whether the transaction is * still valid in the server. This should be checked if the associated * operation did not complete successfully.
  • *
  • baseDNs -- This may specify the set of base DNs below * which the client is allowed to request operations as part of this * transaction. It may be absent if there are no restrictions on which * base DNs may be used, or if it has not changed since the last * response within this transaction.
  • *
