That is, you want an "XML" parser not to enforce basic well
formedness requirements? That'd violate all kinds of fundamental
rules for XML processing. That's not something SAX, or any
other XML API, encourages.

The normal way to do that involves each output stream having
different entity declarations. That means each must have a different
DTD, either with different external subsets or with conditional sections
or (most simply) like
<!ENTITY test "[this is a test]">
Alternatively, some folk have adopted "no DTD" policies for
the data they interchange, and then paste their own DTDs
(with entity declarations) in front of files. It's easy enough to
splice one Reader (or InputStream) in front of another, using
