You might also try this.. This is a modified identity
stylesheet.. I might have missed some template rules
(I think I have).. But you may take the idea! 

Please also consider Mike's answer..

<?xml version="1.0"?> 
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
  
  <xsl:output method="xml" indent="yes" />
  
  <xsl:template match="node() | @*">
    <xsl:copy>       
      <xsl:apply-templates select="node() | @*" />
    </xsl:copy>
  </xsl:template>  
  
  <xsl:template match="p">
    <para>
      <xsl:apply-templates />
    </para>
  </xsl:template>
   
  <xsl:template match="i">
    <render font-style="italic">
      <xsl:apply-templates />
    </render>
  </xsl:template>
  
  <xsl:template match="b/i">
    <render font-weight="bold" font-style="italic">
      <xsl:apply-templates />
    </render>
  </xsl:template>
  
  <xsl:template match="i/sub">
    <render font-style="italic" baseline-shift="sub"
font-size="smaller">
      <xsl:apply-templates />
    </render>
  </xsl:template>  
    
  <xsl:template match="b/i/inf">
    <render font-weight="bold" baseline-shift="sub"
font-size="smaller">
      <xsl:apply-templates />
    </render>
  </xsl:template>
  
  <xsl:template match="b">
    <xsl:apply-templates />
  </xsl:template>
  
  <xsl:template match="b/text()">
    <render font-weight="bold"> 
      <xsl:value-of select="." />
    </render>
  </xsl:template>  
  
</xsl:stylesheet>
