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] ...]
