Question: What happens when a decoder encounters an Extended Element with an unrecognized type in an SMS message?
Option 1: The decoder will terminate the parsing process and discard the entire message.
Option 2: The decoder can skip the unrecognized Extended Element, seeking past it to continue decoding at the next element.
Option 3: The decoder will attempt to interpret the payload data using a default set of rules for unknown types.
Option 4: The decoder will request additional information from the sender to understand the new element type.
Explanation: This behavior ensures backward compatibility and future-proofing, allowing for graceful handling of newly introduced or unrecognized elements without disrupting the decoding process. By skipping the unrecognized element, the integrity of the rest of the message is preserved, enabling the decoder to continue processing known elements effectively.
