 * printing them out in a hard-coded form that probably won't make sense to test
 * candidates but might be useful for debugging.
 *
 * Our implementation additionally adds support for "printing" MathsContent variables
 * used in MathAssess, outputting an inline Presentation MathML element, as documented
 * in the MathAssses spec.
