/**
* SimpleContentModel is a derivative of the abstract content model base
* class that handles a small set of simple content models that are just
* way overkill to give the DFA treatment.
* <p>
* This class handles the following scenarios:
* <ul>
* <li> a
* <li> a?
* <li> a*
* <li> a+
* <li> a,b
* <li> a|b
* </ul>
* <p>
* These all involve a unary operation with one element type, or a binary
* operation with two elements. These are very simple and can be checked
* in a simple way without a DFA and without the overhead of setting up a
* DFA for such a simple check.
