          <p>Yes to the first question, each program requires those
            engines to create its formats.</p>
          <p>As to the second question, no, csplain requires both. It
            contains a format with engine pdftex and a format with
            engine xetex. <br>

    <p>So theTeX Live package "csplain" requires both the PdfTeX format
      and the XeTeX format — OK, that seems reasonable, but what about
      the LuaTeX format — the web resource
