* ARM NEON - accurately described as a Packed SIMD ISA in
all literature.
-* ARM SVE / SVE2 - partially accurately described as a Scalable Vector
- ISA, but the "Scaling" is, rather unfortunately, a parameter
+* ARM SVE / SVE2 - **not a Scalable Vector ISA**, it is actually
+ a hybrid PackedSIMD/PredicatedSIMD ISA.
+ The "Scaling" is, rather unfortunately, a parameter
that is chosen by the *Hardware Architect*, rather than
the programmer. The actual "Scalar" part as far as the programmer
is concerned is supposed to be the Predicate Masks. However in
