| 56 | * Performance Enhancement. The ContentSpecNode constructor always copied the QName
|
---|
| 57 | * that was passed to it. Added a second constructor that allows the QName to be just assigned, not copied.
|
---|
| 58 | * That was because there are some cases in which a temporary QName was constructed, passed to ContentSpecNode, and then deleted.
|
---|
| 59 | * There were examples of that in TraverseSchema and DTDScanner.
