It is an old doc for faa v IACO differences which I presume is ICAO annex 2
Found it again

Trying to find something in EU-ops but that seems to be a restricted document as well.
I have always been taught to follow the missed approach.
I actually find it quite bizarre that nothing is dictated, it must be the only bit of an IFR flight that doesn't have some sort of rule or reg pertaining to its conduct.
Edited to add it seems the previous poster has answered my question mind you Ireland has the way forward in the grand scale of missed approaches. I think straight ahead to 2k everywhere apart from Dublin. Always a pleasure working with Irish ATCO's where ever they are in the world.
