     Animations are implemented as composite states. Each child state of the animation state

   \section1 What Happens If A State Is Exited Before The Animation Has Finished
 
   If a state has property assignments, and the transition into the state has animations for the
   properties, the state can potentially be exited before the properties have been assigned to the
   values defines by the state. This is true in particular when there are transitions out from the
-  state that do not depend on the state being polished, as described in the previous section.
