+# SYNOPSIS
+#
+#   AX_LIB_XML2([MINIMUM-VERSION])
+#
+# DESCRIPTION
+#
+#   This macro provides tests of availability of xml2 'libxml2' library
+#   of particular version or newer.
+#
+#   AX_LIB_LIBXML2 macro takes only one argument which is optional. If
+#   there is no required version passed, then macro does not run version
+#   test.
+#
+#   The --with-libxml2 option takes one of three possible values:
+#
+#   no - do not check for xml2 library
+#
+#   yes - do check for xml2 library in standard locations (xml2-config
+#   should be in the PATH)
+#
+#   path - complete path to xml2-config utility, use this option if xml2-config
+#   can't be found in the PATH
+#
+#   This macro calls:
+#
+#     AC_SUBST(XML2_CFLAGS)
+#     AC_SUBST(XML2_LDFLAGS)
+#     AC_SUBST(XML2_VERSION)
+#
+#   And sets:
+#
+#     HAVE_XML2
