What is a page label

The part of a page that tells the user what page it is
The label is produced by the getLabel method of the page object. In the default layout it is printed by the Header skin as the title of the HTML document, as well as on the top of the page. By default it shows the  type (pntType) and the name (class name) of the page object. This can be overridden, for example for localization, see how to translate page labels.
