                                AttributeBasedElementClassLookup

AttributeBasedElementClassLookup(self, attribute_name, class_mapping, fallback=None) Checks an attribute of an Element and looks up the value in a class dictionary.

Arguments:
  - attribute name - '{ns}name' style string
  - class mapping - Python dict mapping attribute values to Element classes
  - fallback - optional fallback lookup mechanism

A None key in the class mapping will be checked if the attribute is missing.
