The sCnf121 test case requires among others that LPHD.PhyName.serNum and hwRev are present and not empty in the SCL file. After a closer look at clause 6.903.5 this clause does not specify if the values are "configured" in the SCL or read via the MMS interface.
Considering the use case that (broken) hardware can be replaced without changing the configuration it make sense that the serNum and hwRev values are not configured in SCL and have non-empty values when read from the IED via MMS.

Proposal is to require the presence of these attributes in SCL and have non-empty values when read via MMS.

6.903.5 Logical nodes LPHD
LPHD logical nodes shall be as specified in IEC 61850-7-4:2010, 5.3.2, except that the LPHD
logical nodes shall be extended by the addition of the nameplate data objects defined in
Table 903. The value of dataNs data attributes of these extended data objects shall be
“IEC 61869-9:2016”. The data attributes of these extended data objects shall be read-only.
The LPHD data object PhyNam shall conform to the DPL common data class definition in
IEC 61850-7-3:2010, 7.8.2, except that attributes PhyNam.vendor, PhyNam.model,
PhyNam.serNum, PhyNam.hwRev, PhyNam.swRev and PhyNam.d are mandatory and readonly.
For attribute PhyNam.serNum, where the manufacturing date is not implicit in the serial
number, the date of manufacture shall be included.
