      Description

      Currently ODF 1.2 has only 3 possible values for chart:interpolation. Since some ODF implementation have a much larger selection of interpolation types (e.g. closed splines, parabolic splines, cubic csplines, clamped csplines, various step type interpolations), we should add additional ones. I propose that initially we add some step-type interpolations.

      Step type interpolations are useful for various applications such as discrete survival curves as used in Kaplan-Meier analysis.
