That's not possible in that way that you use more or other processes for
the contained analysis engine than for the ruta script. The analysis
engine and the rules can be parallelized together as one analysis engine
namely that one of the script.

You should probably extract the analysis engine into a pipeline, which
applies the analysis engine and then the script (resp. its analysis
engine). Then, the normal UIMA-AS setting applies.
