Use the Ant conductor extension point (dita.conductor.target.relative) to make new targets
    available to the Ant processing pipeline. This can be done as part of creating a new transformation, extending
    pre-processing, or simply to make new Ant targets available to other plug-ins.
    Procedure
- 
        Create an Ant project file that contains the new target.
      
- 
        In the same directory as the Ant project file, create a wrapper file that imports the Ant project file: 
        <dummy>
  <import file="Ant-file"/>
</dummy>
 where
             Ant-file is the project file that contains the new target. 
- 
        Create the plugin.xml file:
        <plugin id="plugin-id">
  <feature extension="dita.conductor.target.relative" file="wrapper-file"/>
</plugin>
 where: 
            - plugin-id is the plug-in identifier, for example,
              com.example.ant.
- wrapper-file is the wrapper file that imports the Ant project file.
 
- 
        Install the plug-in.
      
Results
      The imports from wrapper file are copied into the build.xml file, using the correct path.
        This makes the new Ant targets available to other processes.
