AS2-SMIME : has the certificate to be included inside the signatu re?

Hello,

 

I am new on this list - and I need your help.

 

AS2: when sending a signed message (the original message which can also be
signed, or a signed MDN), has the signer's certificate to be included inside
of the signature MIME part?

Is it mandatory or should AS2 compliant products accept both? (signed
messages containing the cert, or not containing it, in which case they would
try to find a certificate on the local key store etc.) 

 

Regards,
