The qualification of a signature, named as ETSI TS 119 102-2 names signature qualifications.
[Qualification](https://www.jadev-corp.com/api/pdfnetstack-signing/pdfcertificatevalidation/#PdfNetStack_Signing_PdfCertificateValidation_Qualification) reads it from the certificate's
QCStatements alone; [Qualification](https://www.jadev-corp.com/api/pdfnetstack-signing/pdftrustedlistqualification/#PdfNetStack_Signing_PdfTrustedListQualification_Qualification) confirms it
against the EU trusted lists the application supplies, which the library never downloads.

```csharp
public enum PdfQualification
```
