Subject: AC ASN.1

Hi Folks,

Just looking at the "Owner" and "Issuer" fields of the AC as defined in
the latest ac509prof-01 and X.509 FPDAM v6...

The encodings have changed from a CHOICE
(baseCertId, entityName, and objectDigestInfo for Owner
and issuerName, baseCertId for Issuer)

to a SEQUENCE of three OPTIONALs.

What was the reason for this? From the ASN.1, it's now possible to have
BOTH baseCertId/entityName for the owner (plus other combinations).
The same applies to the "Issuer" field.
Is there a restriction to say that only one OPTIONAL must be used, and if
not,
shouldn't one be put in there?

Any info on this would be great.

Thanks,

Andy
