Pre-processing extension points You can use these extension points to run an Ant target before or after the pre-processing stage. If necessary, you can also run an Ant target before a specific pre-processing step — but this approach is not recommended.
depend.preprocess.pre
Runs an Ant target before the pre-processing stage.
depend.preprocess.post
Runs an Ant target after the pre-processing stage.
Legacy pre-processing extensions

The following extension points are available in the original preprocess pipeline that was used by default for all transformations prior to DITA-OT 3.0. These extensions are not available in the newer map-first preprocessing pipeline (preprocess2), which is used in the PDF and HTML Help transformations as of DITA-OT 3.0.

depend.preprocess.chunk.pre
Runs an Ant target before the chunk step in the pre-processing stage.
depend.preprocess.coderef.pre
Runs an Ant target before the coderef step in the pre-processing stage.
depend.preprocess.conref.pre
Runs an Ant target before the conref step in the pre-processing stage.
depend.preprocess.conrefpush.pre
Runs an Ant target before the conrefpush step in the pre-processing stage.
depend.preprocess.clean-temp.pre
Runs an Ant target before the clean-temp step in the pre-processing stage.
