                                          AbstractInstantiationError

Attempt to create an instance of an abstract complex type.

These types are analogous to abstract base classes, and cannot be created directly. A type should be used that extends the abstract class.

When an incoming document is missing the xsi:type attribute which redirects an element with an abstract type to the correct type, the node attribute is provided so the user can get a clue as to where the problem occured. When this exception is a result of constructor mis-use in Python code, the traceback will tell you where the problem lies.
