+       In the XML output, list useless and unused symbols and rules with the
+       useful ones and add a "usefulness" attribute.  Discussed starting at
+       <http://lists.gnu.org/archive/html/bison-patches/2007-09/msg00017.html>.
+       * src/gram.c (grammar_rules_partial_print_xml): Remove.
+       (grammar_rules_print_xml): Print all rules instead of just those
+       useful in the grammar, and add a "usefulness" attribute.
+       * src/gram.h (grammar_rules_partial_print_xml): Remove prototype.
+       * src/print-xml.c (print_rules_useless_in_parser): Remove.
+       (print_grammar): Print all nonterminals instead of just useful ones,
+       and add a "usefulness" attribute to nonterminals and terminals.
+       (print_xml): Don't print a separate "reductions" or
+       "rules-useless-in-parser" element.
+       * src/reduce.c (reduce_output): Use reduce_token_unused_in_grammar.
+       (reduce_xml): Remove.
+       (reduce_token_unused_in_grammar): New.
+       (reduce_nonterminal_useless_in_grammar): New.

+       * data/xslt/xml2xhtml.xsl: Update for XML changes.
+       * tests/reduce.at (Useless Terminals): Update output.
+       (Useless Rules): Update output.
+       (Reduced Automaton): Update output.
+
+       Say "Terminals unused in grammar" instead of "Unused terminals".
+       * NEWS (2.3a+): Update.
+       * doc/bison.texinfo (Understanding): Update example output.
+       * src/reduce.c (reduce_output): Implement.
