10  * XHTMLIndenter: This class indents XHTML elements, by adding whitespace
11  * character data where appropriate. This class differs from its superclass,
12  * HTMLIndenter, only in the way it classifies elements as being inline or
13  * formatted elements: unlike the HTML indenter, it requires the element names
14  * to be in lower case and to be in the XHTML namespace.
