Font Style Language

The font style definition file has an XML syntax with seven elements:

<styles>

The root element that can contain any number of <style> elements.

<style>

Each <style> element must contain one <label> element and one <fontspec> element. It is an error if either of these is missing or appears more than once.

<label>

The name of the style.

If the inner text of this element matches the value of the class attribute in a MathML element, then that MathML element will be stylized according to the <fontspec> element that is a sibling of this <label>.

<fontspec>

This can contain 0-3 of the following three elements which describe the font characteristics of the style. If any of these elements are omitted, the corresponding font characteristic adopts a default value listed below.

• <fontfamily> - Accepted values are any legal font family name, or "inherited". Default is "inherited".
• <fontweight> - Accepted values are "normal", "bold" or "automatic". Default is "automatic".
• <fontslant> - Accepted values are normal, italic or automatic. Default is "automatic".

For example, the following code defines two font styles named my Arial, my Arial2, and myEmphasis:

<styles>

 <style>

  <label>myArial</label>

  <fontspec>

   <fontfamily>Arial</fontfamily>

    <fontweight>normal</fontweight>

    <fontslant>automatic</fontslant>

  </fontspec>

 </style>

 <style>

  <label>myArial2</label>

  <fontspec>

   <fontfamily>Arial</fontfamily>

    <fontweight>bold</fontweight>

   <fontslant>normal</fontslant>

  </fontspec>

 </style>

 <style>

  <label>myEmphasis</label>

  <fontspec>

   <fontfamily>inherited</fontfamily>

    <fontweight>bold</fontweight>

   <fontslant>italic</fontslant>

  </fontspec>

 </style>

</styles>
