RE: Queries on Message/rfc822, Compressed-Data.

Hi Russ,
 
As per draft-ietf-smime-x400transport-05.txt to convey information about the
contained content 
of an S/MIME message in an X.400 transport environment EITs are used. 
 
Section 2.5 (2.5.1 to 2.5.6) of draft-ietf-smime-x400transport-05.txt define
the EITs for:
1. Enveloped Data
2. Signed Data
3. Certificate Management
4. Signed Receipt
5. Enveloped X.400
6. Signed X.400
 
These match with the corresponding EITs defined in
http://www.imc.org/ietf-smime/sm-oid.asn
-- X.400 Encoded Information Types (EIT) for S/MIME objects
id-eit-envelopedData OBJECT IDENTIFIER ::= { id-eit 1 }
id-eit-signedData OBJECT IDENTIFIER ::= { id-eit 2 }
id-eit-certManagement OBJECT IDENTIFIER ::= { id-eit 3 }
id-eit-signedReceipt OBJECT IDENTIFIER ::= { id-eit 4 }
id-eit-envelopedx400 OBJECT IDENTIFIER ::= { id-eit 5 }
id-eit-signedx400 OBJECT IDENTIFIER ::= { id-eit 6 }
 
I am unable to find the corresponding EIT definition for the smime-type
parameter 
'compressed-data'(CompressedData), that has been newly introduced in the
'draft-ietf-smime-
rfc2633bis-03.txt'.

These are both discussed in the most recent MSG draft.
Please see draft-ietf-smime-rfc2633bis-03.txt.

Hi, 

I had the following 2 queries. Would appreciate a response on these if
possible: 

1. Going  through the S/MIME mail archive I find a discussion on the use of
message types like 
    message/rfc822, message/partial etc. that could be used to wrap a
protected message (MIME 
    content + RFC822 Headers). Also as per MOM of the 54th IETF meeting it
seems that 
    message/rfc822 message type has been finalized for this purpose. 

    My question is how should one distinguish such a message ( A protected
message wrapped 
    in message/rfc822) from a forwarded message which also has a message
type of 
    message/rfc822 and can also contain a non protected message? Is an
example message of 
    type message/rfc822 containing a protected message available for
reference? 

2. The latest draft 'S/MIME Version 3.1 Message Specification'
(draft-ietf-smime-rfc2633bis-03.txt) 
    mentions a new S/MIME type "compressed-data". However for this new
S/MIME type no 
    corresponding EIT has been defined in the S/MIME TRANSPORT draft. Where
would one be 
    able to find the corresponding EIT for the same?
