Known Subclasses:
html.HtmlElementClassLookup

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.
