Hi, I'm reading the SPMP spec (v0.9.2) and have a question I couldn't figure out from the document.
§2.1 (Extension Dependencies) lists: "The sstatus.MXR (Make eXecutable Readable) bit must be writable."
However, MXR is never mentioned again anywhere else in the document. The permission encoding (§2.4, Figure 4) and the matching logic (§2.5) do not refer to it.
So my question is simply: what does MXR actually do in the context of SPMP? Does it affect SPMP permission checks in any way, and if not, why is its writability required as a dependency?
A short explanation (or a note in the spec) would be very helpful. Thanks!
