Strange INP field to record named "test"

[AlexanderWells-diamond]

In the ADBase.template file there seems to be an odd record who has an INP field pointing to a record simply named "test":

record(mbbi, "$(P)$(R)ShutterStatusEPICS_RBV")
{
    ...
    field(INP,  "test CP MS")
    ...
}

See file here: https://github.com/areaDetector/ADCore/blame/master/ADApp/Db/ADBase.template#L609

I note that when I start my camera IOC it attempts to form channel access links to the record, which obviously does not exist. Is this simply a remnant of some long forgotten test, or is there some other reason for this link to exist?

I don't think it's an issue. It's explained in https://areadetector.github.io/areaDetector/ADCore/ADDriver.html:

Status of the EPICS-controlled shutter. This record should have its input link (INP) set to a record that contains the open/close status information for the shutter. The link should have the “CP” attribute, so this record processes when the input changes. The ZRVL field should be set to the value of the input link when the shutter is closed, and the ONVL field should be set to the value of the input link when the shutter is open.

So it's being left in simply as an example? From the text it sounds like the INP, ZRVL and ONVL should all be macros, to allow easy substitution of record values?
