You are absolutely right. It's just that these InputModules serve the purpose
of returning small values, and that often multiple times from the same source.
The DatabaseActions make use of this heavily. I wouldn't want to use pipelines
for obtaining 30 values through the use of the request generator and some xslt
resulting in 30 executions of this pipeline.

We all are familiar with xpath, so why not use this to specify what values
should be taken.
