That's only one part of the idea.
There are also speed changes that are ensured by train protection
elements, such as PZB-magnets. [1]
Sure, not all speed changes have such restrictions, it should be an
optional addition to the current <speedChange> element.
Moreover there should be more than one such a reference to different
<trainProtectionElement>s. The Germans use up to three magnets for one
speed aspect. [1]
