+ * encode the attributes field if it is empty. This is in
+ * violation of PKCS#10 but we need to tolerate it. We do
+ * this by making the attributes field OPTIONAL then using
+ * the callback to initialise it to an empty STACK.
+ *
+ * This means that the field will be correctly encoded unless
+ * we NULL out the field.
+ *
+ * As a result we no longer need the req_kludge field because
+ * the information is now contained in the attributes field:
+ * 1. If it is NULL then it's the invalid omission.
+ * 2. If it is empty it is the correct encoding.
+ * 3. If it is not empty then some attributes are present.
