+ * adns will not process the RDATA at all - you'll get intstr's, where
+ * the int is the length and the char* points to the data. String
+ * representation of the RR data is as in RFC3597. adns_rr_info
+ * will not return the type name in *rrtname_r (due to memory management
+ * problems); *fmtname_r will be set to "unknown".
+ *
+ * Do not specify adns_r_unknown along with a known RR type which
+ * requires domain name uncompression. Domain names will not be
+ * uncompressed and the resulting data will be useless. Asking for
+ * meta-RR types via adns_r_unknown will not work properly either
+ * and may make adns complain about server misbehaviour.
