title: What is the categorization name for HTML elements when listed according to function, opposed to content model?
body: <p>The WHATWG, the W3C and Mozilla all categorize the HTML elements by content model, i.e.,: </p>
  
  <ul>
  <li>Metadata content</li>
  <li>Flow content</li>
  <li>Sectioning content</li>
  <li>Heading content</li>
  <li>Phrasing content</li>
  <li>Embedded content</li>
  <li>Interactive content</li>
  <li>Form-associated content</li>
  <li>Transparent content model</li>
  <li>Other content models</li>
  </ul>
  
  <p>(See the <a href="http://www.w3.org/TR/html5/Overview.html#contents" rel="nofollow">W3C's HTML5 spec</a> at <em>3.2.5 Content models</em>)</p>
  
  <p>But they also list HTML elements into another category, like so:</p>
  
  <ul>
  <li>Root element</li>
  <li>Document metadata</li>
  <li>Scripting</li>
  <li>Sections</li>
  <li>Grouping content</li>
  <li>Text-level semantics</li>
  <li>Edits</li>
  <li>Embedded content</li>
  <li>Tabular data</li>
  <li>Forms</li>
  <li>Interactive elements</li>
  </ul>
  
  <p>(See the <a href="http://www.w3.org/TR/html5/Overview.html#contents" rel="nofollow">HTML5 spec</a> at <em>4. The elements of HTML</em>)</p>
  
  <p>Other sources of this grouping are seen in the <a href="http://www.whatwg.org/specs/web-apps/current-work/#auto-toc-4" rel="nofollow">WHATWG's specification</a>, on the <a href="http://developers.whatwg.org/" rel="nofollow">WHATWG Developers subdomain</a>, and from <a href="https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/HTML5/HTML5_element_list" rel="nofollow">Mozilla</a>, so it's a popular labelling convention.</p>
  
  <p>Is there a semantic name for the latter group, aside from the "HTML elements"? Maybe 'functional' or 'structural' list or something to differentiate from the box model list?</p>
