Acrobat v7.0.8 may be used to validate documents to PDF/A-1b compliance. However, Adobe doesn't appear to comply with the standard properly. The specification states that the namespace that should be used to declare the pdfaid prefix, is <
http://www.aiim.org/pdfa/ns/id>. However, Acrobat doesn't like this, it seems to be expecting <
http://www.aiim.org/pdfa/ns/id.html>. When the PDF/A I'm generating is validated using the preflight tool it reports that the "PDF/A label missing". Modifying the namespace address to the "..id.html" above fixes the problem with Acrobat but is not to the standard. Has anybody any idea if/when Adobe intend to address this discrepency?
