The API uses ints instead of the direct DataDefinedProperty enums, as
the enums vary by part of code (there's separate enums for symbology,
labelling, layouts, etc)
For symbology:
layer = QgsSvgMarkerSymbolLayer(...)
...
layer.setDataDefinedProperty( QgsSymbolLayer.PropertyName,
QgsProperty.fromExpression( " some expression ") )

Thanks Nyall, that works!
And now I know the property name, I could also find the other
properties. And then I started searching the code for more and found the
ones listed below. Possibly there are more.
It was apparently too hard for me finding these property names and I
wonder if others are struggling as well. Where could we put this in a
way where people can find it and where it will be easily to maintain?
The cookbook?
