Key Structure Section contains error(s)

Section 12.1 of the rfc states that the format of a V4 Key is as follows:

   Primary-Key
      [Revocation Self Signature]
      [Direct Key Signature...]
      [User ID [Signature ...] ...]
      [User Attribute [Signature ...] ...]
      [[Subkey [Binding-Signature-Revocation]
              Primary-Key-Binding-Signature] ...]

I'm pretty sure however, that in the last line, Primary-Key-Binding-Signature must be replaced by Subkey-Binding-Signature, so that the section reads as:

   Primary-Key
      [Revocation Self Signature]
      [Direct Key Signature...]
      [User ID [Signature ...] ...]
      [User Attribute [Signature ...] ...]
      [[Subkey [Binding-Signature-Revocation]
              Subkey-Binding-Signature] ...]
