// NT5 does not provide any facility to enable/disable auditing at
// audit-event level. It only supports it at audit category level.
// This creates problems if one wants to audit only certain specific
// audit events of a category. The current design gives you all or none for
// each category.
//
// Post NT5 auditing will provide a better/flexible design that wil address
// this issue. For now, to delight some valuable customers, we provide this
// hack / registry based solution. This solution will be removed post NT5.
