--------------------------------------
Type: Technical
Reported by: David von Oheimb <David.von.Oheimb@siemens.com>

Section 5.1.1 says:

Original Text
-------------
In such
a case, the senderKID field MUST hold an identifier (i.e., a
reference number) that indicates to the receiver the appropriate
shared secret information to use to verify the message.

Corrected Text
--------------
If the sender does not know its own DN and
it protects the message using a shared secret,
the senderKID field MUST hold an identifier (i.e., a
reference number) that indicates to the receiver the appropriate
shared secret information to use to verify the message.

Notes
-----
The above extension allows for the following case:
If the sender does not know its own DN
and does not protect the message, providing a senderKID is not relevant.

Instructions:

This erratum is currently posted as "Reported". Please
