Section 12.1. says:
In the above diagram, if the binding signature of a subkey has been revoked, the revoked key may be removed, leaving only one key.
It should say:
In the above diagram, if the binding signature of a subkey has been revoked, the revoked key may be removed. Note that this bears the danger of importing the subkey again without the Binding Signature Revocation.
If there are more than one subkeys, the removing of one leaves more
than one key. And the warning is missing.
Changed to editorial.
