Vern Paxson commented on BIT-1156:

Does "payload of DNS TXT records" mean that an individual TXT record can consist of multiple character strings?  If so, and if the order is significant/preserved, then set[string] wouldn't be the right type.

If instead this is referring to multiple TXT RRs, then likely set[string] is okay (but worth double-checking the RFC regarding the semantics for that case).

> The payload of DNS TXT records can consist of multiple character strings but the DNS analyzer parses out only the first. We should parse them out all and then probably concatenate into a single string to pass to the event, separated with semicolons or something.
> I have a trace with an example but it would need anonymization before inclusion into the test suite.
