possible events in a midi file

Question

I am writing a parser for midi files. This table lists all possible midi messages, however this link describing midi files does not talk about some of the messages, for example, "Song Position Pointer", "Start, "Stop", and others are absent. I am aware that receiving MIDI data from a device is different from reading a MIDI file. Does this mean midi file won't contain all of the events described in the midi table(1st link)? Does the second link describe everything that may be contained in a valid midi file?

Thanks.

Answer 1

System common and real-time messages (F1..FF) cannot appear as events in MIDI files. However, they could be wrapped into an F7 event.
