+  <!-- by animation
+
+       The behaviour at this point is not clear. The definition of by-animation
+       is:
+
+       "simple animation in which the animation function is defined to offset
+       the underlying value for the attribute, using a delta that varies over
+       the course of the simple duration, starting from a delta of 0 and ending
+       with the delta specified with the by attribute." (SMILANIM 3.2.2)
+
+       Therefore it might seem like by-animation of by="1" means to ADD to the
+       underlying scale factor. Furthermore, the underlying scale factor when
+       not otherwise specified might seemt to be 1, but the SVG WG have decided
+       it's 0. This is inconsistent with the definition of addition for
+       animateTransform (post-multiplication of matrices) but it is the
+       behaviour required by SVGT1.2 test suite and used by Opera.
+
+       The following animation should go from 0 to 4, over 2s so at t=1s, the
+       scale factor should be 2.
