 +   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].
