3.12.1 Passing Comments to Backend

  < <comment: Your comment here >>

will produce in HTML and DBX output

  <!-- Your comment here -->

and in TEX output

  ; Your comment here

The difference between ignore and comment is that the former prevents the text from reaching the backend at all while the latter will pass the text to the backend, but use the backend's comment syntax to escape it (so it will typically not render even if it is in the file).

N.B. If you want to pass comments only to a specific type of backend, you can use the backend specific tag, such as < <html: <!-- HTML only comment --> >> < <tex: ; TEX only comment >>
