title: How to generate PDF/UA files? Or convert them from HTML?
body: <p>PDF/UA is a standard for accessible PDF documents. They're also called "tagged PDF's" because they are built using styled tags (like "heading 1") instead of just having a bigger font for headings. This helps in making the document accessible for people with disabilities (such as blind people) who use assistive technology to help them read the file.</p>
  
  <p>I would like to generate such files on my Linux server. Preferably in PHP by converting an accessible HTML document to PDF/UA, but any method that works will do as long as it runs on Linux.</p>
  
  <p>Does anyone know any solution for this? Converting from HTML would be nice because that already would be a tagged document, but I could also settle for putting together the document in a script myself as long as the output is an accessible PDF.</p>
