- * Revision 1.15 1997-12-09 16:18:16 adam
+ * Revision 1.21 1998-06-09 13:55:07 adam
+ * Minor changes.
+ *
+ * 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.
+ *
+ * Revision 1.17 1998/02/11 11:53:34 adam
+ * Changed code so that it compiles as C++.
+ *
+ * Revision 1.16 1997/12/18 10:51:30 adam
+ * Implemented sub-trees feature for schemas - including forward
+ * references.
+ *
+ * Revision 1.15 1997/12/09 16:18:16 adam
* Work on EXPLAIN schema. First implementation of sub-schema facility
* in the *.abs files.
