      determining coordinate systems.
  
        For example, consider a translation whose parent coordinate
!       system is a distortion: all points transformed by the translation
!       also get transformed by the distortion: the value
!       of the distortion transformation at every point
!       is significant.

      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.
