XMLOutputter.NamespaceStack (JDOM v1.SNAPSHOT)

java.lang.Object
- org.jdom.output.XMLOutputter.NamespaceStack

Enclosing class:

XMLOutputter
```
protected class XMLOutputter.NamespaceStack
extends java.lang.Object
```
Our own null subclass of NamespaceStack. This plays a little trick with Java access protection. We want subclasses of XMLOutputter to be able to override protected methods that declare a NamespaceStack parameter, but we don't want to declare the parent NamespaceStack class as public.
