I believe it is well-recognized that the status and severity of a PV reflect the state of the record containing that PV rather than the state of PV value itself.

This is not fully true.
* The "pseudo fields" RTYP and VERS report random (?) status and severity.
* When using monitors on fields, lets say EGU, status and severity are not updated when they change and thus do not reflect the state of the PV.


BTW: Many records have a general problem reporting correct attributes to any field but VAL. For example, reporting the EGU field as the units of the PREC field is obvious nonsense.
