All
A term that is an unordered sequence of terms.
Note that the inheritance structure for this node is unusual. It has multiple children when it is treated as a term tree, but is considered a leaf node when constructing an automaton.

Term that collects an unordered sequence of terms. The terms are provided as arguments. All must be instances of a subclass of Node.

Abstract method that defines nullable for the subclass. The return value should be
|
Create a term tree that implements unordered catenation of the terms. This expansion results in a standard choice/sequence term tree, at the cost of quadratic state expansion because terms are cloned as required to satisfy the tree requirements of the term tree.
