  <!-- These <semantics> elements are content MathML expressions with various annotations. Only the first recognized annotation should be displayed. WebKit recognizes the following annotations:
   - Any <annotation> element without src attribute.
   - An <annotation-xml> element without src attribute and with one of the encoding among "application/mathml-presentation+xml", "MathML-Presentation", "image/svg+xml", "SVG1.1", "application/xhtml+xml" and "text/html".
