//
|
||||
// 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
|
||||
