FltPathOBN:
Read the post immediately above you cited from an ICAO document. Reads pretty much like the FAA's AIM:
ICAO Cite:
A visual approach is not an IAP and therefore has no missed approach segment. If a go-around is necessary for any reason, aircraft operating at controlled airports will be issued an appropriate advisory/clearance/instruction by the tower. At uncontrolled airports, aircraft crews are required to remain clear of clouds and are expected to complete a landing as soon as possible. If a landing cannot be accomplished, the aircraft crew is required to remain clear of clouds, maintain separation from other airport traffic and is expected to contact ATC as soon as possible for further clearance. ATC separation from other IFR aircraft is only assured once further ATC clearance has been received and acknowledged by the aircraft crew.
