What is the question? There is no question within the post. The cell storage (as opposed to the storage for the control structures managing the cell storage, which can be thought of as the "anchor" and the "extent") is not touched by the service. There is one ALET used for the suite of services. That is referred to as the control ALET ("cntl_alet"). It applies to both the anchor and the extent. As one would expect, it does not apply to the cell storage. Whether the ALET represents an address space or data space is unimportant to the system.
What part of the documentation is unclear, so that we can improve it appropriately?
