- * Revision 1.3 1995-11-01 16:34:55 quinn
+ * 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.
+ *
+ * Revision 1.14 1997/10/31 12:20:09 adam
+ * Improved memory debugging for xmalloc/nmem.c. References to NMEM
+ * instead of ODR in n ESPEC-1 handling in source d1_espec.c.
+ * Bug fix: missing fclose in data1_read_espec1.
+ *
+ * Revision 1.13 1997/10/27 13:54:18 adam
+ * Changed structure field in data1 node to be simple string which
+ * is "unknown" to the retrieval system itself.
+ *
+ * Revision 1.12 1997/09/17 12:10:34 adam
+ * YAZ version 1.4.
+ *
+ * Revision 1.11 1997/09/05 09:50:55 adam
+ * Removed global data1_tabpath - uses data1_get_tabpath() instead.
+ *
+ * Revision 1.10 1997/05/14 06:54:01 adam
+ * C++ support.
+ *
+ * Revision 1.9 1997/02/19 14:46:15 adam
+ * The "all" specifier only affects elements that are indexed (and not
+ * all elements).
+ *
+ * Revision 1.8 1997/01/02 10:47:59 quinn
+ * Added optional, physical ANY
+ *
+ * Revision 1.7 1996/06/10 08:56:01 quinn
+ * Work on Summary.
+ *
+ * Revision 1.6 1996/05/31 13:52:21 quinn
+ * Fixed uninitialized variable for local tags in abstract syntax.
+ *
+ * Revision 1.5 1996/05/09 07:27:43 quinn
+ * Multiple local attributes values supported.
+ *
+ * Revision 1.4 1996/05/01 12:45:28 quinn
+ * Support use of local tag names in abs file.
+ *
+ * Revision 1.3 1995/11/01 16:34:55 quinn
* Making data1 look for tables in data1_tabpath
*
* Revision 1.2 1995/11/01 13:54:44 quinn
