Issue

Hi, I'm getting this error when I try to add info element on PDF 2.0. My purpose is custom metadata editing on pdf. Is PDFSharp supporting PDF 2.0 ? If not, can you suggest another package ?

Environtment: .Net 4.8 Framework

Expected Behavior

PdfSharp should open the file and add info element succesfully.

Actual Behavior

Steps to Reproduce the Behavior

    PdfDocument document;
    try
    {
        document = PdfReader.Open(filePath);
        var properties = document.Info.Elements;                
        properties.SetString("/" + key, value);
        document.Save(filePath);
        document = null;                
        return true;
    }
    catch (Exception e)
    {
        if (document != null)
            document = null;
        throw;
    }

PDFsharp does not yet support PDF 2.0.

PDFsharp 6.0.0 should now support PDF 2.0.
