I did a first pass at implementing a SAX 1.0gamma driver for XP today. Some nits: It should be specified whether a byte order mark at the beginning of a XML byte stream is included as part of the character stream. I don't think it should be since the byte-order mark isn't included the XML document production, and the XML spec says explicitly that the byte order mark "is an encoding signature, not part of either the markup or the character data of the XML document". How are relative system identifiers supposed to be handled in DTDHandler? Suppose I have a DTD with a system id of dir/foo.dtd, which declares an unparsed entity with a system id of foo.eps (which refers to dir/foo.eps). If the systemId argument to DTDHandler.unparsedEntityDecl is foo.eps, then the application is going to have problems. There's a similar issue with EntityResolver.resolveEntity. Parser.parse should be allowed to throw IOException in addition to SAXException. Since InputSource includes a Reader and InputStream, and methods on Reader and InputStream throw IOException, parse needs to throw IOException. It's ridiculous to require the parser to wrap an IOException in a SAXException when you know that the parser needs to throw IOException. There's nothing in the XML spec that says parsers have to make attribute types available. So I think the doc for AttributeList.getType should say that CDATA may be returned not only if the parser has not read the declaration, but also if the parser does not make this information available (alternatively it could return null in this case). Supporting changing of Locale in the middle of a parse would require me to redesign my native interface in a way I consider very undesirable, and I don't see any need for this, so I don't plan to support this. The basic issue is that my counterpart of Parser is reentrant unlike SAX's and I want to keep it that way. I think changing of Locale mid-parse is going to be difficult for anyone with a similar style of interface. It's probably too late for this, but I'm having problems seeing the logic in the exception handling design. The design seems to make things inconvenient for both users and implementors: implementors have to wrap SAXException in order to pass it up through their parsers, and in handler methods users have to wrap their exceptions in SAXException.
