Where is the tree-walking stuff in DKIM? I can't find it in the current
draft.

(On an off-topic tangent, because this hasn't been made clear in this
thread so far, the specific problem with CSA and wildcards is that SRV is,
in general, incompatible with wildcards: if you try to blanket a zone with
wildcards in order to ensure that all invalid EHLO names within the zone
have negative CSA SRV records, including those names that do not otherwise
appear in the DNS, then you'll also return bogus SRV data for any SRV
query on any name in your domain. Wildcards are less problematic with
other RR types.)
