How to get the coordinates of a reference point using python?

Hi,
Anyone who knows if it is possible to use python to find the coordinates of a reference point?

My reference points are made based on datumPoint objects, which has a pointOn member. But do not see how I can utilized this.

(Reason why I work with reference points is that they can be included in a geometry set and I have found a way to find the id of the reference point feature. But not how to find the coordinate of the related 'parent' datumPoint.

I would like to work directly with the datumPoints, but as far as I can see it is not possible to collect these in a set and do iterations based on this)
