Timeout: 750 ms

DCP messages containing errors are not regarded as completed until the timeout period has elapsed.
Therefore, it is recommended to wait for this time between DCP messages to allow the parser to handle possible errors.
Correct messages are processed immediately upon completion.
Unknown elements
Unknown tags in a DCP message are ignored for the sake of upwards compatibility of the protocol.
Messages containing unknown elements must still be syntactically correct.
Unknown tags may not be nested deeper than 5 levels.
Empty elements
An empty element is an opening tag immediately followed by a closing tag.
