All OEI and DEP are custom criteria, which is approved by exceptions by the host Country.
While these procedures are in use in many Countries, even some in S America, Africa, and Russia, there is no individual Country which has developed the public criteria in these regards.
There is also no criteria for an RNP-AR missed approach, AE or OE.
If you look at the coding for the procedures, there is the code for APP, which goes to the runway endpoint. Then the coding goes to MISS.
In the FMS, on appraoch, the missed is armed. Because of the coding, only one missed is available.
When you see the chart, there is a common segment, then the OEI continues.
Therefore, when OEI is shown, the entire missed is designed for OEI.
