<h1>Known Issues With MathML</h1>

<p>The following are known Amaya MathML issues:</p>
<ul>
  <li>Amaya implements only the Presentation Tags from MathML 2.0, not the
    Content Markup. All presentation elements and attributes are available,
    but only the following attributes are rendered on the screen:
    <p><code>display, alttext, mathvariant, mathsize, mathcolor,
    mathbackground, fontsize, fontweight, fontstyle, fontfamily, color,
    linethickness, numalign, denomalign, bevelled, notation, lquote, rquote,
    lspace, rspace, largeop, movablelimits, subscriptshift, superscriptshift,
    form, width </code>(mspace only), <code>height</code> (mspace only),
    <code>depth</code> (mspace only), <code>align, rowalign, columnalign,
    frame, framespacing, displaystyle, side, rowspan, columnspan, rowspacing,
    columnspacing, rowlines, columnlines</code> .</p>
  </li>
  <li><span><span>The <code>class</code>, <code>id</code>, and
    <code>style</code> attributes are available, with the same semantics as
    in HTML: you can associate CSS styles with MathML elements
    (<code>class</code> and <code>style</code> attributes) and a MathML
    element can be the target of a link (<code>id
    </code>attribute).</span></span></li>
  <li><span><span>Due to the lack of mathematical fonts in the current
    version, only a limited set of entities representing math symbols are
    recognized, mainly those available in the Symbol font. The current
    version supports the following:</span></span>
    <p><span><code>Therefore, SuchThat, DownTee, Or, And, Not, Exists,
    ForAll, Element, NotElement, NotSubset, Subset, SubsetEqual, Superset,
    SupersetEqual, DoubleLeftArrow, DoubleLeftRightArrow, DoubleRightArrow,
    LeftArrow, LeftRightArrow, RightArrow, Congruent, GreaterEqual, le,
    NotEqual, Proportional, VerticalBar, Union, Intersection, PlusMinus,
    CirclePlus, Sum, Integral, CircleTimes, Product, CenterDot, Diamond,
    PartialD, DoubleDownArrow, DoubleUpArrow, DownArrow, UpArrow,
    ApplyFunction, TripleDot, DifferentialD, ImaginaryI, ExponentialE,
    InvisibleComma, UnderBar, OverBar, ThinSpace, ThickSpace, Hat, OverBar,
    UnderBar, prime, Prime.</code></span></p>
