  * $Log: d1_absyn.c,v $
- * Revision 1.18  1998-02-27 14:08:04  adam
+ * Revision 1.20  1998-05-18 13:07:02  adam
+ * Changed the way attribute sets are handled by the retriaval module.
+ * Extended Explain conversion / schema.
+ * Modified server and client to work with ASN.1 compiled protocol handlers.
+ *
+ * Revision 1.19  1998/03/05 08:15:32  adam
+ * Implemented data1_add_insert_taggeddata utility which is more flexible
+ * than data1_insert_taggeddata.
+ *
+ * Revision 1.18  1998/02/27 14:08:04  adam
  * Added const to some char pointer arguments.
  * Reworked data1_read_node so that it doesn't create a tree with
  * pointers to original "SGML"-buffer.
