CustomElementClassLookup(self, fallback=None) Element class lookup based on a subclass method.

You can inherit from this class and override the method:

lookup(self, type, doc, namespace, name)

to lookup the element class for a node. Arguments of the method: * type: one of 'element', 'comment', 'PI', 'entity' * doc: document that the node is in * namespace: namespace URI of the node (or None for comments/PIs/entities) * name: name of the element/entity, None for comments, target for PIs

If you return None from this method, the fallback will be called.
