The format of a fragmented message is:

&&XXXTN|msg|

where:

• && is the header, just two ampersands, that indicates this is a fragmented message
• XXX is the message id: every fragement of each unique message has the same ID
• T is the kind of messge: 'A' is a fragment, 'B' is the last fragment, 'C' is "missing packets" and 'D' is ACK.
• N is the fragment number
• | is a pipe to indicate the end of the fragment number
• msg is the base64 encoded message
• | ends the message

When an application send an AO to Nuntium it must include "fragment=true" or "fragment=1" as a custom attribute for the message to be gzipped and fragmented. This results in an AO created for the message and AOs created for every fragment of the message as children of this main AO.
