Description

The file created with the example from PDFBOX-3329 fails to validate with VeraPDF because two elements (/Subtype /XML /Type Metadata) in the /Metadata stream dictionary are missing. This is because the third constructor of PDMetadata doesn't add them. Another problem (only for PDF/A-1b in versions 3 and trunk) is that XRef isn't supported, so it should be disabled in the merge.
