Perhaps you are confusing wildcards with CNAME. With CNAME, there
can be no other record type with the same name. There is no such
restriction for wildcards.
I have an example:
*.single-wild.porcupine.org. IN A 168.100.3.4
This returns an A record for foo.single-wild.porcupine.org:
% host -t a foo.single-wild.porcupine.org
foo.single-wild.porcupine.org has address 168.100.3.4
But no TXT record for foo.single-wild.porcupine.org:
% host -t txt foo.single-wild.porcupine.org
foo.single-wild.porcupine.org has no TXT record
Here, the wildcard applies only to A queries.
