So one suggestion is we remove specific errors like single-bit errors,
multi-bit errors and such and limit the features to error handling,
detection and logging/reporting.
So we could drop these statements:
- Main memory must be protected with SECDED-ECC.
- All cache structures must be protected.
- single-bit errors must be detected and corrected.
- multi-bit errors can be detected and reported.

And change this statement to drop the restriction to "these protected structures":
"There must be memory-mapped RAS registers to log detected errors with information about the type and location of the error"

Yes, fine by me. We can make the changes you have suggested above and
leave the remaining content as is.
