//
// 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.
//
// DESCRIPTION:
//
// This guy handles the following scenarios:
//
// a
// a?
// a*
// a+
// a,b
// a|b
//
// 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.
//
// NOTE: Pass the XMLElementDecl::fgPCDataElemId value to represent a
// PCData node. Pass XMLElementDecl::fgInvalidElemId for unused element
//

// The operation that this object represents. Since this class only
// does simple contents, there is only ever a single operation

// Boolean to allow DTDs to validate even with namespace support. */
