+ There has been some confusion about the namespace for the PDF/A indicator in the XMP
+ metadata. At least three variants have been seen in the wild:
+ </p>
+ <table>
+ <tr>
+ <td>http://www.aiim.org/pdfa/ns/id.html</td>
+ <td><strong>obsolete</strong>, from an early draft of ISO-19005-1, used by Adobe Acrobat 7.x</td>
+ </tr>
+ <tr>
+ <td>http://www.aiim.org/pdfa/ns/id</td>
+ <td><strong>obsolete</strong>, found in the original ISO 19005-1:2005 document</td>
+ </tr>
+ <tr>
+ <td>http://www.aiim.org/pdfa/ns/id/</td>
+ <td><strong>correct</strong>, found in the technical corrigendum 1 of ISO 19005-1:2005</td>
+ </tr>
+ </table>
+ <p>
+ If you get an error validating a PDF/A file in Adobe Acrobat 7.x it doesn't mean that
+ FOP did something wrong. It's Acrobat that is at fault. This is fixed in Adobe Acrobat 8.x
+ which uses the correct namespace as described in the technical corrigendum 1.
