Here's what I have for a switchyard config in my M1 test application:

<switchyard xmlns="http://www.switchyard.org/config/model/switchyard/v1"
    targetNamespace="org.example.m1/m1-dry-run-0.0.1-SNAPSHOT" 
    xmlns:sca="http://docs.oasis-open.org/ns/opencsa/sca/200912"
    xmlns:soap="urn:switchyard:soap-binding:1.0"
    name="m1app">
    <sca:composite>
        <sca:service name="SimpleService" promote="SimpleService">
            <soap:binding.soap>
                <soap:serverPort>18001</soap:serverPort>
                <soap:wsdl>wsdl/SimpleService.wsdl</soap:wsdl>
            </soap:binding.soap>
        </sca:service>
        <sca:component name="SimpleService">
            <sca:implementation.bean
                class="org.switchyard.example.deployable.SimpleServiceBean" />
            <sca:service name="SimpleService">
                <sca:interface.java interface="org.switchyard.example.deployable.SimpleService" />
            </sca:service>
            <sca:reference name="AnotherService">
                <sca:interface.java interface="org.switchyard.example.deployable.AnotherService" />
            </sca:reference>
        </sca:component>
        <sca:component name="AnotherService">
            <sca:implementation.bean
                class="org.switchyard.example.deployable.AnotherServiceBean" />
            <sca:service name="AnotherService">
                <sca:interface.java interface="org.switchyard.example.deployable.AnotherService" />
            </sca:service>
        </sca:component>
    </sca:composite>
</switchyard>

We need a bean component scanner that integrates with the configuration plugin to produce the following parts of the above definition from @Service and @Reference annotations.  Note that we also need a bean marshaller, model implementation, and XSD for the "bean" namespace.

<sca:component name="SimpleService">
   <bean:implementation.bean class="org.switchyard.example.deployable.SimpleServiceBean" />
   <sca:service name="SimpleService">
      <sca:interface.java interface="org.switchyard.example.deployable.SimpleService" />
   </sca:service>
   <sca:reference name="AnotherService">
      <sca:interface.java interface="org.switchyard.example.deployable.AnotherService" />
   </sca:reference>
</sca:component>
<sca:component name="AnotherService">
   <bean:implementation.bean class="org.switchyard.example.deployable.AnotherServiceBean" />
   <sca:service name="AnotherService">
      <sca:interface.java interface="org.switchyard.example.deployable.AnotherService" />
   </sca:service>
</sca:component>
