Should deploymentResouces in SpringProcessEngineConfiguration match *.bpmn pattern only?

[gul]

I have my activiti process definition xml's as below:
/src/main/resources/processes/activiti/process1-activiti.xml
/src/main/resources/processes/activiti/process2-activiti.xml
/src/main/resources/processes/activiti/process3-activiti.xml

and I am referring them through SpringProcessEngineConfiguration bean  in /processes/process-context.xml

<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
      <property name="dataSource" ref="ACT_JdbcDataSource" />
      <property name="transactionManager" ref="ACT_transactionManager" />
       <property name="databaseSchemaUpdate" value="true" />
      <property name="jobExecutorActivate" value="false" />
      <property name="asyncExecutorEnabled" value="true" />
      <property name="asyncExecutorActivate" value="true" />
      <property name="deploymentResources" value="classpath*:/processes/activiti/*-activiti.xml" />
   </bean>

but non of the resources get deployed.  Is it mandatory for the process definition xml's to end with ".bpmn.xml"?

The spring process engine config will pick them up, but the engine won't do anything with it unless it's .bpmn or .bpmn20.xml
