thank you for your valuable input from a Norwegian point of view!
From technical side, two possible solutions are possible:
1) extending the value list for <gradientCurve>@curveType replacing the
value "mixed" with new values "maximum" and "average".
2) adding a new attribute <gradientCurve>@aggregationReference with
values "maximum" and "average", which is only set in case of
<gradientCurve>@curveType="mixed".
I prefer solution 1), but the more interesting question for me is if
there are further types of "mixed" gradients apart of maximum and average.
Any feedback is highly appreciated...
Best regards
Christian
