It is possible to have "invisible arguments" to a callback that do not complicate the interface. This sounds very mysterious, but an "invisible argument" is just a variable whose value can be fetched through a parser method. getCurrentEntity() or getFileEncoding() would be examples. I think that this is the right way to handle this entity problem. Require the parser to track the information rather than the application.
