* 24-bits are needed within the main SVP64 Prefix (equivalent to a 2-bit XO)
* Another 24-bit (a second 2-bit XO) is needed for a planned future encoding,
currently named "SVP64-Single" [^likeext001]
-* A third 24-bits (third 2-bit XO) is strongly recommended to be **reserved**
+* A third 24-bits (third 2-bit XO) is strongly recommended to be `RESERVED`
such that future unforeseen capability is needed.
* To hold all Vector Context, five SPRs are needed for userspace.
