| // |
| // 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 ids. |
| // |

| // |
| // fOp |
| // The operation that this object represents. Since this class only |
| // does simple contents, there is only ever a single operation |
| // involved (i.e. the children of the operation are always one or |
| // two leafs.) |
