public class SimpleContentModel extends java.lang.Object implements ContentModelValidator
This class handles the following scenarios:
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.

children
- The children of this element. Each integer is an index within
the StringPool
of the child element name. An index
