           <h3>Grammar</h3>
           <p>A N-Quads document is a Unicode[[!UNICODE]] character string encoded in UTF-8.
           Unicode codepoints only in the range U+0 to U+10FFFF inclusive are allowed.</p>
+          <p>White space (tab <code>U+0009</code> or space <code>U+0020</code>) is used to separate two terminals which would otherwise be (mis-)recognized as one terminal. White space is significant in the production <a href="#grammar-production-STRING_LITERAL_QUOTE">STRING_LITERAL_QUOTE</a>.</p>
+          <p>Comments in N-Quads take the form of '<code>#</code>', outside an <code>IRIREF</code> or <code>STRING_LITERAL_QUOTE</code>, and continue to the end of line (<code>EOL</code>) or end of file if there is no end of line after the comment marker. Comments are treated as white space.</p>
           <p>The <abbr title="Extended Backus–Naur Form">EBNF</abbr> used here is defined in XML 1.0
