/**
 * This event is used when a node changes in a non-structural way.
 * Non-structural, that is, as far as the IStructuredDocument is concerned.
 * The whole node, along with the new text is sent, just in case a listener
 * (e.g. a tree model) might make its own determination of what to do, and
 * need the whole node to act appropriately.
 * 
 * Note: users should not make assumptions about whether the node is literally
 * the same instance or not -- it is currently a different instance that is
 * identical to the old except for the changed region, but this implementation
 * may change.
