Hmm, I think I begin to see how it should work. Thanks for the
explanation!
However, (before actually trying) it still seems to me to be much
easier to rewrite a piece of the stock ASB than use UIMA-AS with complex
pipeline construed by UIMAfit... So I think I will try that first (and
report back).

The intention is to do both, latency is also important for me
as I have an interactive user interface for the pipeline.
