 ====== Open Questions/Comments ======
   - D: Maybe the overall description comment should start with '###' as in Python to distinguish from normal '#' comments which the parser should just ignore
-    * S: The proposal concerning '#' is a really tricky thing. I am not sure we should do this. However, at the moment I don't have a better proposal.
+    * S: The proposal concerning '#' is a really tricky thing. How about including three single quotes like in python docstrings? or /* description*/ like in c++
   - D: See 'detectorobj' description: A 'take external' selection could clearly point out those objects which have to be defined on a fundamental level in whatever program one uses
   - D: What is the difference between 'doc' and 'code'? Can't the 'doc' contain everything, including the code?
      * N: 'doc' is a link to a human-readable document.  'code' is the name of the function/link to the function (for when they make a library of functions).
   - D: What is the purpose of 'eff' in the cuts and what distinguishes a 'trigger' selection from a normal 'select'?
-     * There is no difference between 'trigger' and 'cut'.  In the original version, one could have aribitrary xml tags, so I thought it'd be nice to have explicit names.  Now, everything should be a 'cut'.
+     * N: There is no difference between 'trigger' and 'cut'.  In the original version, one could have aribitrary xml tags, so I thought it'd be nice to have explicit names.  Now, everything should be a 'cut'.
      * N: The eff is an estimated efficiency for things like the trigger/b-tagging etc. provided by the experiments.  We should in principle also allow inclusion of efficiency tables instead of a single number.
   - D: In cuts, I again would rather use 'take' instead of 'contains': if 'B' uses the events from A, then 'A takes the events from B' (but 'B contains the events from A, as A applies more cuts')

+Issues:
+  - pt-selection, identification, overlap removal, isolation are sometimes done in alternating order. This can lead to a plethora of detector-obj.
+  - cuts can be very hard to read and even hard to parse. Maybe one could improve on that
