I proposed that we have three different Java interfaces for call-backs (I can now supply package names as well): org.xml.sax.EntityHandler org.xml.sax.DocumentHandler org.xml.sax.ErrorHandler There are setters for all of these in the parser interface, org.xml.sax.Parser: package org.xml.sax; public interface Parser { public void setEntityHandler (EntityHandler handler); public void setDocumentHandler (DocumentHandler handler); public void setErrorHandler (ErrorHandler handler); public void parse (String publicID, String systemID) throws Exception; } To create an interface that delivers more information, we could simply define a new interface, say, org.xml.FancyHandler, and then extend the Parser interface: package org.xml.sax; public interface FancyParser extends Parser { public void setFancyHandler (FancyHandler handler); } I see no reason that we cannot turn our attention to this issue once the current SAX is implemented and relatively stable -- at least, we have not shut the door to future enhancement.
