    <p>
      This document describes how the <a
      href="http://www.w3.org/TR/SVG/interact.html#PointerEventsProperty">SVG
      pointer-events property</a> is extended for use in (X)HTML content.
    </p>

    <!-- ======================================================================================================= -->

    <h2>
      2 The <span class="prop-name">pointer-events</span> property
    </h2>
    
    <p>
      In different circumstances, authors may want to control under what
      circumstances particular elements can become the target of pointer
      events. For example, the author might want a given element to ignore
      pointer events under all circumstances so that elements underneath the
      given element will become the target of pointer events.
    </p>

    <p>
      The 'pointer-events' property specifies under what circumstances a given
      element can be the target element for a pointer event. It
      affects the circumstances under which the following are processed:
    </p>
    
    <ul>
      <li>user interface events such as mouse clicks</li>
      <li>dynamic pseudo-classes (i.e., :hover, :active and :focus)</li>
      <li>hyperlinks</li>
    </ul>
    
    <p>
      The <span class="prop-name">pointer-events</span> property was originally defined for <a
      href="http://www.w3.org/TR/SVG/interact.html#PointerEventsProperty">SVG content</a>
      and, as such, accepts property values specific to vector graphics (eg. relating to
      graphical fill and stroke). The following definition only applies to the property
      when used with HTML content. Note that the property has a new initial value, "auto",
      which behaves as "visiblePainted" in SVG content and "visible" in non-SVG content.
