11 * Defines an API for reporting error messages by the validator. The

12 * API is a struct of function pointers (i.e. virtuals) which will

13 * be called by the validator to print out error messages.

14 *

15 * The typical error message is generated using the form:

17 * error_reporter->printf(format, ...)

18 *
