+/* This is the ASN1_AUX structure: it handles various
+ * miscellaneous requirements. For example the use of
+ * reference counts and an informational callback.
+ *
+ * The "informational callback" is called at various
+ * points during the ASN1 encoding and decoding. It can
+ * be used to provide minor customisation of the structures
+ * used. This is most useful where the supplied routines
+ * *almost* do the right thing but need some extra help
+ * at a few points. If the callback returns zero then
+ * it is assumed a fatal error has occurred and the
+ * main operation should be abandoned.
+ *
+ * If major changes in the default behaviour are required
+ * then an external type is more appropriate.
