      <p>
        This test verifies both the initial viewport size and the support for the various
        unit specifiers.
      </p>
      <p>
        The units in SVG can be: user coordinate and CSS units: em, ex, px, pt, pc, cm, mm,
        in and percentages. The test does not check the absolute length accuracy as this
        can only be truly validated with a ruler. However, it validates that the different
        units are supported by drawing multiple elements who have the same length specified
        in different units.
      </p>
      <p>
        The viewport is the "finite rectangular region" where rendering occurs in SVG.
        Hence, nothing should be rendered outside the viewport (paragraph 7.1). Furthermore,
        when no positioning properties are set on the top svg element, the initial viewport
        size should have the value of the top svg element's "width" and "height" attributes.
        To check this behavior, the test does not define positioning properties on the top
        svg element but defines its "width" and "height" properties. Then it fills a red
        rectangle that is bigger than the viewport size. Then, a rectangle, the size of the
        viewport is drawn in white. If rendering is limited to the viewport area, none of the
        red should show.
      </p>
      <p>
        The line showing the "ex" units will not necessarily appear with the same length
        as shown in the reference image because the X-height of a font is not
        necessarily half of the font size (which is assumed in the reference image where
        1ex is considered to be .5em).
      </p>

    <d:passCriteria xmlns="http://www.w3.org/1999/xhtml">
      <p>The test passes if the top three lines (user units, px, em) are the same length,
      the fifth line (%) is the same length as the top three lines, and the bottom
      five lines (in, cm, mm, pt, pc) are the same length.  The fourth line (ex) may have
      any non-zero length, since the X-height of the font will depend on the exact font
      chosen by the user agent (which may vary).</p>
