Jim,

I agree that it should read differently, however see minor 
change below:

Given the addition of SKI to SignerInfo, the following 
change should be made
in section 5.4 of ESS.

First pargraph after ASN is:

The first certificate identified in the sequence of 
certificate identifiers
MUST be the certificate used to verify the signature. The 
encoding of the
ESSCertID for this certificate SHOULD NOT include the 
issuerSerial because
the issuerAndSerialNumber is already present in the SignerInfo. The
certificate identified is used during the signature 
verification process. If
the hash of the certificate does not match the certificate 
used to verify
the signature, the signature MUST be considered invalid.

Paragraph should be:

The first certificate identified in the sequence of 
certificate identifiers
MUST be the certificate used to verify the signature.  The 
encoding of the
ESSCertID for this certificate SHOULD include the 
issuerSerial field.  If
other constraints ensure that issuerAndSerialNumber will be 
present in the
SignerInfo, ESSCertID MAY be omitted. The certificate 
identified is used
during the signature verification process. If the hash of 
the certificate
does not match the certificate used to verify the signature, 
the signature
MUST be considered invalid.

Should it not read as follow instead:

The first certificate identified in the sequence of 
certificate identifiers
MUST be the certificate used to verify the signature.  The 
encoding of the
ESSCertID for this certificate SHOULD include the 
issuerSerial field.  If
other constraints ensure that issuerAndSerialNumber will be 
present in the
SignerInfo, the issuerSerial field MAY be omitted. The certificate
identified is used during the signature verification process. 
If the hash
of the certificate does not match the certificate used to verify the
signature, the signature MUST be considered invalid.
