That is correct.  From the 3.14.12.5 application developer's guide:

Field name The field name, which must be a valid C identifier. When include files are generated, the field name is
converted to lower case. Previous versions of EPICS required the field name be a maximum of four characters,
but this restriction no longer applies.

OK, the test I am now using is: if the name ends with '.' and up to four uppercase letters which are not 'VAL' then ignore the status/severity. It seems to be working OK.  As for non-IOC PVs, I'll  cross that bridge when I come to it.

Isn't it allowed for a record's field to have more than 4 characters? It's not common but the CCDImageServer (pre-area detector software) included field names with more than 4 characters and also included one or more "." in some cases.
