55 When using MIME <xref target="MIME" /> to encapsulate a
56 structured object that
57 consist of many elements, for example an SGML <xref target="SGML" />
58 document, a
59 single element may occur several times. An encapsulation normally
60 maps each of the structured objects elements to a MIME entity. It is
61 useful to include elements that occur multiple time exactly once. To
62 accomplish that and to preserve the object structure it is desirable
63 to unambiguously refer to another body part of the same message.

114 Consider a MIME multipart entity several of whose body parts contain
115 the same data (body) but different parameters or Content-* headers.
116 Representing those body parts without duplicating the data in each
117 one promotes efficient use of resources (bandwidth and storage
118 space). To achieve these benefits an access-type is defined that
119 permits one message part to refer to another one in the same message.

163 The content-id header of the access-type=content-id MIME
164 entity must match (be identical to) exactly one content-id

167 within a multipart message and can refer to another body
