I am not sure how easy this is in Java, but in Delphi/C++ one would
use a var parameter, pre-set to the most likely value, so that
in the normal case the programmer would not do anything about it.

In Java you might use a status object, whose state is preset?

In Expat (SAX-like, but not SAX) we are going to add a status to the
callback signatures. This is for the purpose of adding a Pull API, 
while still keeping the Push API. In Pull mode the callbacks will act
as "filters" (status = Continue, Stop, Error, ...), in Push mode one
can use them directly.
