I think 212man had the answer to your original question about the source of the chapter and verse you want, if not the reference itself.
By the way I have included the definition of MAP as some people may be expecting it to be MAPt.
Try
PANS OPS Flight Procedures (Doc 8168)
3.6.1.3
The missed approach point (MAP) in a procedure may be:
a.the point of intersection of an electronic glide path with the applicable DA/H; or
b.a navigational facility; or
c.a fix; or
d.a specified distance from the final approach fix (FAF).
When the MAP is defined by a navigational facility or a fix, the distance from the FAF to the MAP is normally published as well, and may be used for timing to the MAP. In all cases where timing may not be used, the procedure shall be annotated “timing not authorized for defining the MAP”.
1.6.2
Operators may specify two types of approach procedures for non-precision approaches. The first is that described as: “descend immediately to not below the minimum stepdown fix altitude/height or MDA/H as appropriate”. This method is acceptable as long as the achieved descent gradient remains below 15 per cent and the missed approach is initiated at or before the MAP. Alternatively, operators are encouraged to use a stabilized approach technique for non-precision approaches. This technique requires a continuous descent with a rate of descent adjusted to achieve a constant descent gradient to a point 15m (50 ft) above threshold, taking due regard of the minimum crossing altitudes/heights specified for the FAF and any prescribed stepdown fix. If the required visual reference approaching MDA/H is not achieved, or if the MAP is reached before reaching the MDA/H, the missed approach must be initiated. In either case, aircraft are not permitted to go below the MDA/H at any time. The stabilized approach technique is also associated with operator-specified limits of speed, power, configuration and displacement at (a) specified height(s) designed to ensure the stability of the approach path and a requirement for an immediate go-around if these requirements are not met.
Hope that helps.
