4.6 Detailed Components With An ATTACH Property

   This example shows the format of a message containing a group meeting
   between three individuals. The multipart/related encapsulation is
   used because the iCalendar object contains an ATTACH property that
   uses a CID to reference the attachment.

5 Recommended Practices

   This section outlines a series of recommended practices when using a
   messaging transport to exchange iCalendar objects.

5.1 Use of Content and Message IDs

   The [iCAL] specification makes frequent use of the URI for data types
   in properties such as "DESCRIPTION", "ATTACH", "CONTACT" and others.
   Two forms of URIs are Message ID (MID) and Content ID (CID). These
   are defined in [RFC-2111]. Although [RFC-2111] allows referencing
   messages or MIME body parts in other MIME entities or stores, it is
   strongly recommended that iMIP implementations include all referenced
   messages and body parts in a single MIME entity. Simply put, if an
   iCalendar object contains CID or MID references to other messages or
   body parts, implementations should ensure that these messages and/or
   body parts are transmitted with the iCalendar object. If they are not
   there is no guarantee that the receiving "CU" will have the access or
   the authorization to view those objects.
