Re: Content Type Attribute Question

Russ,

    Sorry about the delayed reply.  Been busy with other lives...

    I guess I'd still rather see an open ended field in the
encapsulatedContentType attribute, but the union of the existing attribute and
contentHints does address much of my concern.  Why do we have two attributes
to describe the encapsulated content rather than one?  If the semantics of
contentHint can be bent as far as MIME content types, then it seems like they
should be the same attribute.

Thanks.  The contentType attribue is defined in CMS, and it already has an
OID.

I will assign an OID for the encapsulatedContentType attribute.  In fact,
I'll do it now ... I assigned:

    id-smime OBJECT IDENTIFIER ::= { iso(1) member-body(2) us(840)
            rsadsi(113549) pkcs(1) pkcs-9(9) 16 }

    id-aa   OBJECT IDENTIFIER ::= { id-smime 2 }

    id-aa-encapContentType OBJECT IDENTIFIER ::= { id-aa 6 }

Russ,

ESS, Sec 1.3.4 already lists encapsulatedContentType as a separate
attribute.  This is needed to provide equivalent services as the ACP120
encapsulatedContentType.

Please note that the ESS Open Issues (Appendix D) states that OIDs still
need to be defined for the contentType and encapsulatedContentType
attributes.
