sorry, now I understand, that the table is not applicable 
for animateMotion using a path attribute or a mpath 
element. This part of the problem was my error.
The second can simply be avoided by removing 
'control' from 'control point'.

Something related:
The distance definition of transform list type rotate
seems to be a little bit strange (physical argumentation), 
because it mixes up angles and lengths. 
Because they have different units, calculations according 
to this will lead to funny effects, comparing the same 
animation with just a coordinate system scaled differently 
for lengths.
It is maybe more useful to define the distances for
the angle and the translation independently, using
a replacement like 
translate(-cx,-cy) rotate(angleA) translate(cx,cy)
and the distance definitions for value types angle
and transform list type translate.

Best wishes
