the following patch looks like a reasonably-minimal patch to add SRV
support:
http://tinydns.org/srv-patch
Attached is a debdiff that applies it to 1:1.05-9~exp1, and works fine
-- i'm happy to go ahead and upload this to experimental if that's ok
with you, Gerrit.
let me know,

+Subject: tinydns-data SRV & axfr-get SRV/PTR patches
+Date: Thu, 14 Sep 2000 20:37:50 -0400
+
+Here's a combined patch that:
+
+a) adds a native SRV type to tinydns-data
+
+Sfqdn:ip:x:port:weight:priority:ttl:timestamp
+
+Standard rules for ip, x, ttl, and timestamp apply. Port, weight, and
+priority all range from 0-65535. Weight and priority are optional; they
+default to zero if not provided.
+
+Sconsole.zoinks.example.com:1.2.3.4:rack102-con1:2001:69:7:300:
+
+b) makes axfr-get decompose SRV and PTR records and write them out in
+native format, rather than opaque. Again, this is necessary because if the
+DNAME fields in the records reference the same zone as fqdn, they can have
+compression pointers that are bogus outside the context of that specific
+packet, and which can't be correctly loaded into data.cdb by tinydns-data.
