ResponseItem subclasses do not write answers to XML
Several of the classes that override the ResponseItem abstract method generateXML have the ability to store a correct answer. None of them, however, include this in the XML representation they generate.

Since we aren't asking the user to specify what the correct answer is as part of the parsing process, this would be a non-trivial task to complete. Therefore I'm pushing it off to the post-prototype stage.
This is tied to the notion of rubric, and we've decided that we won't support rubrics at the prototype stage.
