+
+ Automate regression testing of the XML/XSLT implementation. Discussed
+ starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2007-11/msg00021.html>.
+ * configure.ac (XSLTPROC): New substitution.
+ * Makefile.am (maintainer-xml-check): New phony target invoking...
+ * tests/Makefile.am (maintainer-xml-check): ... this new phony target
+ invoking make maintainer-check with BISON_TEST_XML=1.
+ * tests/atlocal.in (XSLTPROC): New.
+ * tests/local.at (AT_BISON_CHECK): New macro to (1) instruct Valgrind
+ not to report reachable memory when Bison is expected to have a
+ non-zero exit status and (2) to compare XML/XSLT output with --graph
+ and --report=all output for every working grammar when
+ BISON_TEST_XML=1.
+ (AT_BISON_CHECK_NO_XML): Likewise, but skip XML checks.
+ (AT_BISON_CHECK_XML): New.
+ (AT_QUELL_VALGRIND): New.
+ * tests/testsuite.at (ORIGINAL_AT_CHECK): Remove this and...
+ (AT_CHECK): ... don't redefine this since this was the old way to
+ quell Valgrind.
+ * tests/actions.at: Rewrite all AT_CHECK invocations for bison as
+ AT_BISON_CHECK invocations.
+ * tests/c++.at: Likewise.
+ * tests/calc.at: Likewise.
+ * tests/conflicts.at: Likewise.
+ * tests/cxx-type.at: Likewise.
+ * tests/existing.at: Likewise.
+ * tests/glr-regression.at: Likewise.
+ * tests/headers.at: Likewise.
+ * tests/input.at: Likewise.
+ * tests/java.at: Likewise.
+ * tests/output.at: Likewise.
+ * tests/push.at: Likewise.
+ * tests/reduce.at: Likewise.
+ * tests/regression.at: Likewise.
+ * tests/sets.at: Likewise.
+ * tests/skeletons.at: Likewise.
+ * tests/synclines.at: Likewise.
+ * tests/torture.at: Likewise.
+ (Big triangle): Use AT_BISON_CHECK_NO_XML instead since this grammar
+ tends to hang xsltproc.
+ (Big horizontal): Likewise.

In XML output, remove redundant class attribute on symbol element.
