Funnily enough I was just having a conversation with Dave Thompson about this very thing. When I mentioned that we will have a "-I exi" option for the command line tool, which from Daffodil's perspective will be just like using SAX, he asked if he will need to specify the "-I sax" option, or if that option will just go away.
I am in full agreement of removing the "-I sax" option as, like you said, SAX usage is inherently an API and I can't think of an easy way to pass a SAX ContentHandler over the command line. Adding an EXI option to the Daffodil CLI tool can kill 2 birds with one stone in that we will be adding support for EXI as well as demonstrating how to pass in your own SAX ContentHandler.

In the CLI, there is the -I option to specify infoset-type. One of the choices is 'sax'. This is a mistake I think. This is really "XML text by way of calling the SAX API". It's effectively a testing mode for us. SAX usage is inherently an API. I believe we should remove this feature from the CLI, because it creates a lot of confusion. It requires test-mode things to be in the main-libraries where the CLI can find them. If we require SAX to be used as it is intended, from applications calling Daffodil via APIs, then all this "xml text to/from SAX-event" code all ends up in src/test where it belongs. Thoughts?
