Active cannot go to cancelled, because 'cancelled' means cancelled before commencing. The equivalent for an active Instruction is to go to 'aborted' (i.e. 'cancel' something running).
Scheduled => Expired is a good one - we should add that for sure.
Postponed => Cancelled is also a good one we missed.
Agree on improving the documentation as you say.

Looking at http://www.openehr.org/releases/RM/latest/docs/ehr/ehr.html#_the_standard_instruction_state_machine_ism
It seems these might be valid transitions but are not represented in the state diagram:
ACTIVE -> CANCELLED
SCHEDULED -> EXPIRED
POSTPONED -> CANCELLED
does this makes sense?
are there any other missing transitions?
Off topic but related, we might want to improve the state descriptions, small example, for the INITIAL state it would be useful to mention it is a virtual state that is there just to make the state diagram valid (have one initial state), and also to use UML state diagrams (https://en.wikipedia.org/wiki/State_diagram_(UML))
I would like to know others opinions about that ^
