| michael@0 | 11 | * @update gess 7/20/98 |
| michael@0 | 12 | * |
| michael@0 | 13 | * This interface defines standard interface for DTD's. Note that this |
| michael@0 | 14 | * isn't HTML specific. DTD's have several functions within the parser |
| michael@0 | 15 | * system: |
| michael@0 | 16 | * 1) To coordinate the consumption of an input stream via the |
| michael@0 | 17 | * parser |
| michael@0 | 18 | * 2) To serve as proxy to represent the containment rules of the |
| michael@0 | 19 | * underlying document |
| michael@0 | 20 | * 3) To offer autodetection services to the parser (mainly for doc |
| michael@0 | 21 | * conversion) |
