Description copied from interface: IWemListenerList

This method is used to notify about a new list. Each list contain at least one list item. All list items are notified using the IWemListenerList.beginListItem()/IWemListenerList.endListItem() method pair. Items of lists of this type can contain the following sequence of elements:

1. formatted text - the text can be empty; in this case it is not notified
2. Just after the text the list item can have:
   • an embedded list - in this way it is possible to build hierarchical structures
