                                          AbstractElementError

Attempt to create an instance of an abstract element.

Raised when an element is created and the identified binding is abstract. Such elements cannot be created directly; instead the creation must derive from an instance of the abstract element's substitution group.

Since members of the substitution group self-identify using the substitutionGroup attribute, there is no general way to find the set of elements which would be acceptable in place of the abstract element.
