-  <p>This specification depends on the Web IDL and HTML5
-  specifications. <a href="#refsWEBIDL">[WEBIDL]</a> <a
-  href="#refsHTML5">[HTML5]</a></p>
-
-
-  <h3>Terminology</h3>
-
-  <p>This specification relies heavily on the HTML5 specification to
-  define underlying terms.</p>
-
-  <p>HTML5 defines the concept of DOM <dfn>collections</dfn> and the
-  <dfn><code>HTMLCollection</code></dfn> interface, as well as the
-  concept of IDL attributes <dfn title="reflect">reflecting</dfn>
-  content attributes. It also defines <dfn>tree order</dfn> and the
-  concept of a node's <dfn>home subtree</dfn>.</p>
-
-  <p>HTML5 defines the terms <dfn>URL</dfn>, <dfn>valid URL</dfn>,
-  <dfn>absolute URL</dfn>, and <dfn>resolve a URL</dfn>.</p>
-
-  <p>HTML5 defines the terms <dfn>alphanumeric ASCII characters</dfn>,
-  <dfn>space characters</dfn> <dfn>split a string on spaces</dfn>,
-  <dfn>converted to ASCII uppercase</dfn>, and <dfn>prefix
-  match</dfn>.</p>
-
-  <p>HTML5 defines the meaning of the term <dfn>HTML elements</dfn>, as
-  well as all the elements referenced in this specification. It also
-  defines the <dfn><code>HTMLElement</code></dfn> and
-  <dfn><code>HTMLDocument</code></dfn> interfaces. It defines the
-  specific concept of <dfn>the <code>title</code> element</dfn> in the
-  context of an <code>HTMLDocument</code>. In the context of content
-  models it defines the terms <dfn>flow content</dfn> and
-  <dfn>phrasing content</dfn>. It also defines what an element's <dfn
-  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>boolean attribute</dfn>, of an <dfn>unordered
-  set of unique space-separated tokens</dfn>, of a <dfn>valid
-  non-negative integer</dfn>, of a <dfn
-  title="concept-date">date</dfn>, a <dfn
-  title="concept-time">time</dfn>, a <dfn
-  title="concept-datetime">global date and time</dfn>, a <dfn>valid
-  date string</dfn>, and a <dfn>valid global date and time
-  string</dfn>.</p>
-
-  <p>HTML5 defines what <dfn>the document's current address</dfn>
-  is.</p>
-
-  <p>Finally, HTML5 also defines the concepts of <dfn>drag-and-drop
-  initialization steps</dfn> and of the <dfn>list of dragged
-  nodes</dfn>, which come up in the context of drag-and-drop
-  interfaces.</p>
