It is important to note that unlike v3.1 64-bit prefixed instructions
there is insufficient space in `RM` to provide identification of
any SVP64 Fields without first partially decoding the
-32-bit suffix. Extreme caution and care must therefore be taken
+32-bit suffix. Similar to the "Forms" (X-Form, D-Form) the
+`RM` format is individually associated with every instruction.

+Extreme caution and care must therefore be taken
when extending SVP64 in future, to not create unnecessary relationships
between prefix and suffix that could complicate decoding, adding latency.
