Nope, nope, nope. In particular, I still have a project to finish
a standard EntityResolver that understands Socats. By having such
a thing, you can fit Socat support into arbitrary applications using
arbitrary SAX parsers. Keep it. As for DTDHandler, it exposes
stuff that XML 1.0 requires a parser to expose.
> 1. Filter Interface
I propose a fourth alternative: provide ParserFilter as a helper
class, and don't have a separate interface. Parser filters are
just parsers that have a "parser(Parser)" constructor.
One particularly nice feature of this is that it is the pattern
used by Java {Input,Output}Streams and Readers/Writers: Chain of
Responsibility.
> 2. Lexical Event Handler
I'll post on this later.
