This rule enforces R.3, so I've added a link to R.3 in the Core Guidelines.

 # C26406  DONT_ASSIGN_RAW_TO_OWNER
+This warning enforces R.3 from the C++ Core Guidelines, see [C++ Core Guidelines R.3](https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#r3-a-raw-pointer-a-t-is-non-owning) for additional information.
 
 Owners are initialized from allocations or from other owners. Assigning a value from a raw pointer to an owner pointer is not allowed. Raw pointers don’t guarantee ownership transfer; there is still may be an original owner which holds the resource and will attempt to release it. Note that assigning a value from owner to a raw pointer is fine; raw pointers are valid clients to access resources, but not to manage them.
