Since the word "and" is used between postpone and suppress, the literal meaning would be that postponing the interruption is required, i.e. the mechanism must make the interruption reappear. I'm assuming this is not the intent. If so, I would recommend changing to "postpone or permanently suppress" to make the options clear.

Also, if postponing is an option, I'd highly recommend requiring a minimum time before the interruption reappears.

The latter part of this requirement is dangling (i.e. "but also..." only contains a prepositional phrase). I'd like to help with rewording, but I'm confused by the intent of this bullet versus the previous one. They both seem to be dealing with scope of the setting. Can you clarify the distinction?

  • Replace "screen" with "webpage", which has an existing glossary definition
  • Delete "and the path and control conforms to all of this document". This is not only implied in my opinion, but also does not specify a conformance level and conflicts/overlaps with Note 2 in the definition of mechanism.
  • "Reachable" is not defined and so this requirement is very vague. Technically, if I need to click Settings and then jump through 10 pages of controls to get to the mechanism for suppressing the interruption, that is reachable.

If the intent here is to be able to suppress with a single click, then maybe something like: "able to be set without any change of content".
