Calling those "registers" might be technically correct, but rather misleading in my opinion.  These are really RAM locations.  Probably for historical reasons, Microchip refers to RAM bytes in some of its microcontrollers as "registers" sometimes.

Change "Complete Register List" to "Complete Variables List", and "Register Name" to "Variable Name", and I think the confusion disappears.  It should also be obvious in another way that these are not registers with specific hardware meaning, because those are all in bank 15.  Since the addresses are explicitly given, we can see these variables are all in Bank 0.
