//
//  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
//
