For both `/src/SOL003/General_Definitions/SOL003_def.yaml` and `src/SOL002/General_Definitions/SOL002_def.yaml` They not have the proper definition for the Checksum type ```yaml Checksum: #no definition found description: > Cheksum description type: string ``` That may be because SOL003 and SOL002 do not define the type by themselves. They refer to SOL004 instead. Incorrectly, I’ll add, as this was moved into SOL013 as of NFVSOL(20)000237r1. Anyway, the proper definition is now in SOL013 section 7.1.7 The yaml equivalent of the defintion would be ```yaml Checksum: description: Description should be in sync with SOL013 7.1.7 type: object required: - algorithm - hash properties: algorithm: description: Description should be in sync with SOL013 7.1.7 type: string hash: description: Description should be in sync with SOL013 7.1.7 type: string ```
