+	    <p>A mechanism for limiting the amount of text that the
+	    built-in error logger events will produce has been
+	    introduced. It is useful for limiting both the size of
+	    log files and the CPU time used to produce them.</p>
+	    <p>This mechanism is experimental in the sense that it
+	    may be changed if it turns out that it does not solve the
+	    problem it is supposed to solve. In that case, there may
+	    be backward incompatible improvements to this
+	    mechanism.</p>
+	    <p>See the documentation for the config parameter
+	    <c>error_logger_format_depth</c> in the Kernel
+	    application for information about how to turn on this
