Detailed Description
(This is rare.) Examples are transformations and profiles.
Subclasses may need to override the push() method to copy values from the next instance in the stack (using getNextInStack() ), if the new one has to accumulate values on top of the old ones.
This class defines the matches() method to compare lists of node-id's. The node-id's represent the states of all nodes that changed the value of the element. SoAccumulatedElement provides methods that maintain lists of node-id's of all nodes that affect an instance. Subclasses must call these methods to make sure the id's are up to date, if they plan to use the standard matches() method. Otherwise, they can define matches() differently, if they wish.
