There is a "MIN_SAMPLE_SHADING" value in the [0,1] interval which is set by glMinSampleShading(clampf value). It tells the minimum ratio of samples that must be individually shaded. For instance, if you're doing 4xMSAA and mss=0.75, then you must shade at least 3 samples. Always shading all of them as soon as mss is non-zero is compliant to the spec. Always shading all of them all the time is actually compliant to the spec, as far as I can say, but would be a bad idea.
