Regarding naming...
Do we want
org.jaxen.dom4j.Dom4jNavigator
org.jaxen.dom4j.Dom4jJaXPath
org.jaxen.jdom.JdomNavigator
org.jaxen.jdom.JdomJaXPath
or
org.jaxen.dom4j.Navigator
org.jaxen.dom4j.JaXPath
org.jaxen.jdom.Navigator
org.jaxen.jdom.JaXPath
Case #1 avoid possible ambiguities.
Case #2 makes code more portable across object-models, as
all that's needed to change from JDOM to dom4j would be
to alter the import statemenets.
Bueller?
