+AutoDNSSEC is a feature where a DNS provider can automatically manage
+DNSSEC for a domain. Not all providers support this.
+
+At this time, AUTODNSSEC_ON takes no parameters.  There is no ability
+to tune what the DNS provider sets, no algorithm choice.  We simply
+ask that they follow their defaults when enabling a no-fuss DNSSEC
+data model.
+
+NOTE: No parenthesis should follow these keywords.  That is, the
+correct syntax is `AUTODNSSEC_ON` not `AUTODNSSEC_ON()`
