+  title="concept-ID">ID</dfn> or <dfn>language</dfn> is in HTML.</p>
+
+  <p>HTML5 defines the set of <dfn>global attributes</dfn>, as well as
   terms used in describing attributes and their processing, such as
-  the concept of a <dfn id="boolean-attribute">boolean attribute</dfn>, of an <dfn id="unordered-set-of-unique-space-separated-tokens">unordered
