+Note (from [[http://www.dlib.org/dlib/november10/noonan/11noonan.html]]
+   The PDF/A-1 standard provides two levels of compliance:
+   PDF/A-1a denotes "full compliance" and ensures the preservation of a document's logical
+   structure and content text stream in natural reading order. The text extraction is
+   especially important when the document must be displayed on a mobile device (for example
+   a PDA) or other devices in accordance with Section 508 of the US Rehabilitation Act. In
+   such cases, the text must be reorganized on the limited screen size (re-flow). This
+   feature is also known as "Tagged PDFs."
+   PDF/A-1b denotes "minimal compliance" and ensures that the text (and additional content)
+   can be correctly displayed, but does not guarantee that extracted text will be legible
+   or comprehensible. It therefore does not guarantee compliance with Section 508 [4].
