|
|
*
|
|
* This interface defines standard interface for DTD's. Note that this
|
|
* isn't HTML specific. DTD's have several functions within the parser
|
|
* system:
|
|
* 1) To coordinate the consumption of an input stream via the
|
|
* parser
|
|
* 2) To serve as proxy to represent the containment rules of the
|
|
* underlying document
|
|
* 3) To offer autodetection services to the parser (mainly for doc
|
|
* conversion)
