Customization of the DocBook XSL Stylesheets for the TCC

The application, guibutton, guiicon, guilabel, and guimenu elements are marked up in italic sans-serif type to make them stand out from the body font.

<xsl:template match="application|guibutton|guiicon|guilabel|guimenu">
  <xsl:call-template name="inline.italicsansseq"/>
</xsl:template>
