public class DTDGenerator
extends org.xml.sax.helpers.DefaultHandler

DTDGenerator
Generates a possible DTD from an XML document instance. Pure SAX version of the Saxon DTDGenerator The program has no remaining dependencies on Saxon; all it needs is: JAXP 1.1 SAX2 A JAXP 1.1 conformant XML parser Java 1.2
