> Hi Hendrik
> I am not against or for using the sequence but shouldn't this field be generic to support ECDSA/ DSA or RSA key length? 

The situation is different for ECDSA and RSA. For ECDSA we use different OIDs in the certTemplate to specify the different curves and therefore also for the different key length. For RSA there is only one OID available and this is not specifying a specific key length. Therefore we think it is sufficient to separately specify only the key length for RSA.
