RFC 4034, "Resource Records for the DNS Security Extensions", March 2005

Source of RFC: dnsext (int)

Status: Rejected

Section 3.1.3 says:

   The value of the Labels field MUST NOT count either the null (root)
   label that terminates the owner name or the wildcard label (if
   present).

It should say:

   The value of the Labels field MUST NOT count either the null (root)
   label that terminates the owner name or the leftmost label if
   it is a wildcard.

Notes:

In RFC 4035, section 2.2, describing the same count uses this: ... "and not counting the leftmost label if it is a wildcard" to omit the leading wildcard label. (In 4034, the wildcard label is defined as "*" earlier in the same problematic section.)

The text in 4034 could be confused with having to count "wildcard labels" in the middle of a name, such as in name.*.tld. The reason for suggesting this errata is for compliance considerations.
--VERIFIER NOTES--
All wildcard labels start with * in the leftmost label. No other kind of wildcard label exists.

From RFC 1034:

4.3.3. Wildcards

In the previous algorithm, special treatment was given to RRs with owner
names starting with the label "*".
