As I've originaly noted - this will not work if

www IN A 10.1.2.3
or
www6 IN AAAA 2001:1::80
or
mailme IN MX 10.2.3.4

will appear in DNS configuration.

nslookup -q=txt www
or
nslookup -q=txt www6
or
nslookup -q=txt mailme

will not return your wildcard.
You have to add IN TXT records for them manualy (or modify DNS server
software).
A bunch of TXT records, IMHO.
Secondary servers requesting domain zone transfers will be unhappy ;-)

You are correct, that will not work in the manner described and
additional txt records are required. 

The question then becomes, is this necessary if the server is
"described" in another fashion (i.e. has other resources records
pointing to it that are covered by a published SPF record) ?
