TeacherAnswerValueA matching response does not imply the given response is correct.
Your subclass can implement this method by calling the default method
#isMatchDefault(StudentResponseValue).
The semantics of your problem type might prevent your AnswerValue subclass from calling the isMatchDefault(StudentResponseValue) method.
One case is when the problem type does not implement a 1:1 matching of answer value parts to response value parts.
For example: A range problem is not going to match the student's response (with a single value part) to the answer value parts (which represent a lower- and upper-limit). Rather the range problem must provide an isMatch() implementation that checks if the student's response, a single-part answer value, falls between the two limits.
