[MEV.spdx.txt](https://github.com/user-attachments/files/19091266/MEV.spdx.txt) ``` pyspdxtools -i MEV.spdx ``` gives no error, so the SPDX SBOM is valid. However, as there is no `FilesAnalyzed`, it defaults to true so `PackageVerificationCode` is mandatory. So the SBOM should be flagged as invalid.
