|

| 119 | //
|

|
---|
| 121 | //
|
---|
| 122 | // a
|

| 123 | // a?
|
---|
| 124 | // a*

|
---|
| 127 | // a|b
|
---|
| 128 | //
|
---|
| 129 | // These all involve a unary operation with one element type, or a binary
|
---|
| 130 | // operation with two elements. These are very simple and can be checked
|
---|
| 131 | // in a simple way without a DFA and without the overhead of setting up a
|
---|
| 132 | // DFA for such a simple check.
|
---|
| 133 | //
|
---|
| 134 | // NOTE: Pass the XMLElementDecl::fgPCDataElemId value to represent a
|
---|
| 135 | // PCData node. Pass XMLElementDecl::fgInvalidElemId for unused element
