Note critically that:
-* SVP64 may **not** hold any Scalar operations. There is no free available space.
+*Unlike EXT001 SVP64's 24-bits may **not** hold also any Scalar operations.
+ There is no free available space: a 25th bit would be required.
The entire 24-bits is **required** for the abstracted Hardware-Looping Concept
- **even when these 24-bits are zero*
+ **even when these 24-bits are zero**
* Any Scalar 64-bit instruction (regardless of how it is encoded) is unsafe to
then Vectorise because this creates the situation of Prefixed-Prefixed,
resulting in deep complexity in Hardware Decode at a critical juncture, as
