latest Edition of DOC 4444 specifies that in case of SIDs if your want aircraft to climb higher than the level prescribed in the SIDs or in case of STAR to descend aircraft below level specified in the STAR, the controller need to say that " Cancel level restriction of the SID/STAR and climb or descent to ____ level.
From the Mother doc
6.3.2.4 CLIMB CLEARANCE ABOVE LEVELS SPECIFIED IN A SID
When a departing aircraft on a SID is cleared to climb to a level higher than the initially cleared level or the level(s) specified in a SID, the aircraft shall follow the published vertical profile of a SID, unless such restrictions are explicitly cancelled by ATC.
6.5.2.4 DESCENT BELOW LEVELS SPECIFIED IN A STAR
When an arriving aircraft on a STAR is cleared to descend to a level lower than the level or the level(s) specified in a STAR, the aircraft shall follow the published vertical profile of a STAR, unless such restrictions are explicitly cancelled by ATC. Published minimum levels based on terrain clearance shall always be applied.
11.4.2.6.2.5 Level restrictions issued by ATC in air-ground communications shall be repeated in conjunction with subsequent level clearances in order to remain in effect.
I hope it makes things clear for both pilot and ATC
