Feature request #17054
importing/exporting to sld should use a rotation by field value if available

In qgis you can set a rotation for a symbol based on a attribute value (see screenshot).
This dynamic rotation is not exported to or imported from an SLD
I haven't checked but the same issue probably exists for setting symbol size based on an attribute value
