Customization of the 4.3 DocBook-XSL Stylesheets for the TCC

Page 324 of Section 1.1, “Bob Stayton's DocBook XSL: The complete guide” recommends a style rule for typesetting simple inline math formulae: enclose them in <phrase role='math'>…</phrase>. The corresponding rule sets letters in italics:

<xsl:template match="phrase[@role='math']">
  <xsl:call-template name="inline.italicseq"/>
</xsl:template>
