 //! \brief The value for `EXC_MASK_ALL` appropriate for the operating system at
 //!     run time.
 //!
 //! The SDK’s definition of `EXC_MASK_ALL` has changed over time, with later
 //! versions containing more bits set than earlier versions. However, older
 //! kernels will reject exception masks that contain bits set that they don’t
 //! recognize. Calling this function will return a value for `EXC_MASK_ALL`
 //! appropriate for the system at run time.
 //!
-//! \note `EXC_MASK_ALL` does not include the value of `EXC_MASK_CRASH`.
-//!     Consumers that want `EXC_MASK_ALL` along with `EXC_MASK_CRASH` must use
-//!     ExcMaskAll() | `EXC_MASK_CRASH` explicitly.
+//! \note `EXC_MASK_ALL` does not include the value of `EXC_MASK_CRASH` or
+//!     `EXC_MASK_CORPSE_NOTIFY`. Consumers that want `EXC_MASK_ALL` along with

+//!     the operating system at run time.
+//!
+//! `EXC_MASK_ALL`, and thus ExcMaskAll(), never includes the value of
+//! `EXC_MASK_CRASH` or `EXC_MASK_CORPSE_NOTIFY`. For situations where an
+//! exception mask corresponding to every possible exception understood by the
+//! running kernel is desired, use this function instead.
+//!
+//! Should new exception types be introduced in the future, this function will
+//! be updated to include their bits in the returned mask value when run time
+//! support is present.
