### MODULE

CosTransactions_SubtransactionAwareResource

### MODULE SUMMARY

This module implements the OMG CosTransactions::SubtransactionAwareResource interface.

### DESCRIPTION

This interface inherits the CosTransactions::Resource interface. Hence, it must also support all operations defined in the Resource interface.
