+	  <p>A very uncommon combination of zone data has been found

+	    the data returned in answer to a recursive query.</p>
+	  <p>A recursive resolver that is performing DNSSEC validation

+	    cause a query to be performed against a maliciously
+	    constructed zone.  This will result in a denial of
