Can xAP messages be concatenated, fragmented, sequenced or “chunked”?
All these questions are usually driving at the same thing: can you split a large message over multiple xAP messages, given that the maximum xAP message size across all networks is 1,500 bytes. There is no support within the xAP protocol for sending messages with a payload which spans more than one message. This could be added at the application layer, but is discouraged; a better approach would be to pass the details of how to retrieve the data associated with a larger message over an alternative medium (e.g. the URL of a web server, perhaps).
