 Description
-    A coordinateRotation defined in the z-x-y Euler convention.
+    A coordinateRotation defined in the z-x-z (intrinsic) Euler convention.
+
+    The 3 rotations are defined in the Euler intrinsic convention
+    (around Z, around X' and around Z'').
+    The order of the parameter arguments matches this rotation order.
 
-    The 3 rotations are defined in the Euler convention
-    (around Z, around X' and around Z').

     Note, however, that it is the reverse transformation
     (local->global) that is defined here.
