mmmh. not sure how to answer this question exactly. I guess it's a
design decision. I am not saying that it is best one, but it seemed
suitable to me. I am certainly open to suggestions. But here are some
1) My boss needs to be able to read the input and make sense out of it.
XML seems fairly self explanatory, at least when you choose suitable
names for the properties/tags etc ...
2) I want reproducability of a given run without changes to the code.
I.e. all the inputs need to be stored external to the code such that the
state of the run is captured from the input files entirely.

That is certainly a possibility and it should work. However, eventually
the input files might be written by a webinterface (likely php). Even
though what you are suggesting is still possible it just feels a little
awkward (i.e. to use php to write a python file).
