I'm not sure. RFC 3183 says:
An S/MIME signed attribute is used to indicate the type of signature.
This should be used in conjunction with the naming conventions
specified in the previous section. When an S/MIME signed message
containing the signature type attribute is received it triggers the
software to verify that the correct naming convention has been used.
The ASN.1 [4] notation of this attribute is: -
SignatureType ::= SEQUENCE OF OBJECT IDENTIFIER
It seems to me that the specification fails to also say that the signature
type attribute is identified by
id-aa-signatureType OBJECT IDENTIFIER ::= { id-aa 28 }

Mistype -
RFC 3183 seems to be where it started from - but is now using a different
marker. However, it seems to have been overloaded in a strange way. I
think this may be a fault in the way the RFC progressed.

Subject: [smime] SignatureType Attribute OID
The S/MIME arc contains an assignment for this OID.
id-smime OBJECT IDENTIFIER ::= { iso(1) member-body(2)
us(840) rsadsi(113549) pkcs(1) pkcs9(9) 16 }
id-aa OBJECT IDENTIFIER ::= { id-smime 2 } -- attributes
id-aa-signatureType OBJECT IDENTIFIER ::= { id-aa 28 }
I cannot find an RFC that makes use of this OID. Does anyone know where
it
it used? It seems to be related to the Domain Security stuff in RFC 3183,
but
it is not used in that document.
If no one can point me to a place where this OID is used, I will mark it
"reserved and obsolete".
