I don't use the dns_message event in the base scripts for DNS so what is and what is not set when that event fires is currently undefined.  Also, I'm a little unsure about what you suspect is unset in the output from your short script?

If you want to look at the data that ends up being inserted into the logs, you can look at it this way...

event DNS::log_dns(rec: DNS::Info)
	print rec;
