Derived coordinate system types can have entirely different
sets and interpretations of determining coordinate systems.
+
+ For example, consider again the case of the distortion
+ coordinate system as a parent. But this time, let's
+ make an anchor coordinate system inside it, and
+ make a buoytrans system use it. This time, only the
+ value of the distortion coordinate system at
+ the origin of the anchor coordinate system matters!
+ This value can be used to create a normal translation.
