The Attachment datatype is used to convey a reference to or the actual contents of some type of file-based information such as a pdf document, jpeg image, etc. The key elements of the Attachment datatype are:

Attachment (format and size) is given below:

• contentType (code) (required): the ‘mime type’ of the file content, common values for show below:

• language (code) (Optional): en: English, ar: Arabic
• data (base64Binary) (is required if no url is provided): the attachment to be Base64 encoded and placed in this element.
• url (url)( is required if no data is provided)This is the location of the attachment content
• size (unsignedInt) (required if an url is provided): Number of bytes of content (if url provided)
• hash (base64Binary) (required if an url is provided) : Hash of the data (sha-1, base64ed)
• title (string) (required): Label to display in place of the data, or the name of the file
• creation (dateTime) (required): Date attachment content was first created

• Differential Table
• Key Elements Table
• Snapshot Table
• Statistics/References
• All
