I don't think you can reduce this code all that much, but you can certainly
avoid repeating it. Simplest way is to put it in a named template, but I
would be tempted to use template rules, along the lines:

<xsl:template match="h3">
  ...
  <xsl:attribute name="style">
    <xsl:apply-templates select="@*"/>
  </xsl:attribute>
  ...
</xsl:template>


<xsl:template match="@bold[.='true']">font-weight:bold;</xsl:template>
<xsl:template match="@italic[.='true']">font-style:italic;</xsl:template>


etc
