+ * Revision 1.33  1997-12-18 10:51:30  adam
+ * Implemented sub-trees feature for schemas - including forward
+ * references.
+ *
+ * Revision 1.32  1997/12/09 16:18:16  adam
+ * Work on EXPLAIN schema. First implementation of sub-schema facility
+ * in the *.abs files.
+ *
+ * Revision 1.31  1997/11/18 09:51:08  adam
+ * Removed element num_children from data1_node. Minor changes in
+ * data1 to Explain.
+ *
+ * Revision 1.30  1997/10/31 12:20:07  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 1.29  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 1.28  1997/10/06 09:37:53  adam
+ * Added prototype for data1_get_map_buf.
+ *
+ * Revision 1.27  1997/09/24 13:35:44  adam
+ * Added two members to data1_marctab to ease reading of weird MARC records.
