  <module>CosTransactions_SubtransactionAwareResource</module>
  <modulesummary>This module implements the OMG CosTransactions::SubtransactionAwareResource interface.</modulesummary>
  <description>
    <p>This interface inherits the CosTransactions::Resource interface. Hence, 
      it must also support all operations defined in the Resource interface.</p>
    <p>To get access to the record definitions for the structures use:      <br></br>
<c>-include_lib("cosTransactions/include/CosTransactions.hrl").</c></p>
