sorry for answering so late, but I just recovered from 5 weeks of
illness, so that I missed your posting.
A <gradientCurve> with @curveType="mixed" can be used to model a
gradient curve with an "administrative" gradient value. Imagine the
situation that you have a track from A to B and somewhere on this track
a maximum slope of 25 per mille has to be climbed by the train, but you
don't know exactly, where this gradient appears. In that case, you can
model a <gradientCurve> covering the whole track from A to B with
@gradient="25". By setting @curveType="mixed" it becomes clear, that the
gradient of 25 per mille does not affect the whole track from A to B.
If the community knows further examples where different types of
gradients shall be modelled, please share them here with us in the forum
so that we can discuss them and integrate them in planned Advanced
Example and in the Track Geometry use case.
Thank you very much and best regards
Christian
