Dear Victor,
the PDF/A-1b standard supports PDF-1.4 only and thus object stream
compression is not permitted. It seems that the pdfx package does
the right thing.
The PDF/A-2 and PDF/A-3 standards are less restrictive.

Reinhard

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
