Interface XMLDocumentHandler

All Known Implementing Classes:
DOMParser, SAXParser
public interface XMLDocumentHandler

EntityHandler have with an object that serves as a pluggable validator. This abstraction allows validators for XML grammar languages to be plugged in and queried for validity checks as the scanner processes a document.

The document scanner and entity handler need to ask the validator object for this information because the validator object is responsible for reading the grammar specification file (which contains markup declarations and entity declarations)
