True, but the mention of "dfn" is a link to what the spec says about the
<dfn> element, where it is explained.

Why?  There are things that can be done with a <span> that has no
attributes, for example:

* <span> can delimit a term which is defined elsewhere in the document
  (with a <dfn>).

* Even without a class or id attribute, <span> can still be selected in
  CSS for special styling, for example with this HTML:

    <p class="fruit"><span>Apples</span>, <span>bananas</span>, and
    <span>cherries</span> are all fruit.</p>

  those <span> elements can be distinguished with something like:

    .fruit > span { color: lime; }

  without requiring the class to be applied to each <span> individually.
