Which <mgmtCmd> types are cancellable?
TS-0004 clauses 7.4.16.2.4, 7.4.17.2.1 and 7.4.17.2.3 refer to determining "If the related management operations are cancellable, by checking the cmdType attribute." However they doon't say how you are supposed to determine this from that attribute. Are some command types inherently cancellable and others not - or is an implementation allowed to decide which ones should be cancellable?
