Unionist, perhaps I'm missing something, but if the third paragraph does indeed say
in all cases, level restrictions issued explicitly by ATC in airground communications shall be repeated in conjunction with subsequent level clearances in order for such level restrictions to remain in effect
(my bold), it would appear to be referring not to
published SID/STAR restrictions but to
"restrictions issued explicitly by ATC in airground communications" (ie. unpublished, verbally-issued instructions), and thus in line with my (and your) understanding of ICAO standard?
Regardless, the fact that we are even discussing it underscores how confusing the issue has become, and confusion in altitude selection is a recipe for big problem-la.
