The Outline usually automatically updates the nodes based on the document changes.
If the developer sets an AuthorOutlineCustomizer or an AuthorBreadCrumbCustomizer which uses as render text
for a node the information available in another node, if the second node changes, the Outline/Bread Crumb components
do not know what other nodes to update.
If the developer renders for a <chapter> the gathered text from the <title> child nodes then he will have to add
a document listener and when a <title> node's text changes update the parent <chapter>.
