| 2234 | AttachmentGrp | Attchmnt | optional |
The AttachmentGrp component provides the ability to attach other media type documents to a FIX message for transmission. The media type can be any of the media types (previously referred to as MIME types) that are listed by [IANA](www.iana.org) [RFC2046](http://www.iana.org/assignments/media-types/index.html).
The AttachmentGrp is intended to be used to attach documents or payloads in other encodings, such as XML, JSON, TTL, SBE, GPB, PDF, TIFF, jpg to a FIX message.
Note when the AttachmentGrp is used within a application message, such as the TradeCaptureReport(35=AE), the attachment should supplement the data already contained in the application message. It is not intended to replace the content of the business message. The standard fields within the application message should be populated, even if they duplicate data expressed within the attachment(s).
