Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.

Your question is not concrete and is posted in the wrong forum, emproccess is more adequate but I am sure the detailed answer in any case difficult.
Geant4 itself does not have original cross section data sets. Usually, evaluated cross sections from NIST, ICRU, other organization are extracted and included into Geant4 data file. Part of our data are taken directly from journal publications, part are results of computation on-fly in run time by a corresponding model class.
Geant4 is open source, you can examine public release and conclude what is useful for your purpose.
