 === Hypervisor Exception Delegation Register (hedeleg)
 
-The <<hedeleg>> register operates as described in the RISC-V Privileged
-Specification. At position 28, a new bit is added to <<hedeleg>>
-when the implementation supports {cheri_base_ext_name}. This allows CHERI
-exceptions to be delegated to VS mode.
+Bit 28 of <<hedeleg>> now refers to a valid exception and so can be used to
+delegate CHERI exceptions to virtual supervisor mode.
