# Integrating a new transform type

Plug-ins may integrate an entire new transform type. The new transform type can be very simple, such as an XHTML build that creates an additional control file; it can also be very complex, adding any number of new processing steps.

The transtype extension point is used to define a new "transtype", or transform type, which makes use of targets in your Ant extensions. When a transform type is defined, the build expects Ant code to be integrated to define the transform process. The Ant code must define a target based on the name of the transform type; if the transform type is "mystuff", the Ant code must define a target named dita2mystuff.

`dita.conductor.transtype.check`
  Add new value to list of valid transformation type names.
`dita.transtype.print`
  Declare transtype as a print type.

## Example

The following feature defines a transform type of "newtext" and declares it as a print type; using this transform type will cause the build to look for a target `dita2newtext`, defined in a related Ant extension from the third feature:

    <plugin id="com.example.newtext">
      <feature extension="dita.conductor.transtype.check" value="newtext"/>
      <feature extension="dita.transtype.print" value="newtext"/>
      <feature extension="dita.conductor.target.relative" file="antWrapper.xml"/>
    </plugin>
