Hi all,
I signed a pdf with an invisible external signature.
Acrobat Reader 8 says that signature validity is unknown because signer's
identity is unknown and that's right.
But now I also need to create a PDF/A compliant signed pdf.
I'm able to create a PDF/A compliant pdf and also to modify an existing one
through a PdfStamper without removing that compliance.
But after signing a pdf/a compliant pdf, Acrobat Reader 8 returns report
code 4000: unrecognized pdf content.
I attach also a simple file as a sample of the problem.

What's the problem?
Thanx
