 All of the parameters described in the table above are marked as optional. This is true
 as long as at least one parameter is defined in the setup of the transformation.

+The behavior of the transformation depends on which parameters are used in the setup.
 For instance, if a rate of change parameter is specified a kinematic version of the
 transformation is used.

+The Molodensky transformation is simple to implement and to parametrize, requiring
 only the 3 shifts between the input and output frame, and the corresponding
 differences between the semimajor axes and flattening parameters of the reference
 ellipsoids. Due to its algorithmic simplicity, it was popular prior to the
