Battery passport identifier and digitalProductPassportId

[luisramosbosch]

BatteryPass Long List 1.3.0 requires a (Unique) battery passport identifier.

I was not able to find such attribute with exact matching name, but found digitalProductPassportId in dpp_metadata.

Thus, I wonder if both attributes are equivalent?.

Moreover, BatteryPass Long List 1.3.0 includes:

DPP Schema version
DPP Status
DPP Granularity
Date-time of latest update of DPP
Unique economic operator identifier

Which I assume are the same as:

granularity, dppSchemaVersion, dppStatus, lastUpdate in dpp_metadata, but I do not find in which BatteryPass aspect these attributes were included.
