This works for what I'm doing. Display is down to the 'driver' which 
includes this code.
Just returns boolean pass/fail.

<!-- Integer compare -->
  <xsl:function name="d:int-cmp" as="xs:boolean">
    <xsl:param name="n1" as="xs:integer"/>
    <xsl:param name="n2" as="xs:integer"/>
    <xsl:choose>
      <xsl:when test="$n1 = $n2">
        <xsl:value-of select="true()"/>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="false()"/>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:function>

<!-- Double compare -->
 <xsl:function name="d:double-cmp" as="xs:boolean">
    <xsl:param name="n1" as="xs:double"/>
    <xsl:param name="n2" as="xs:double"/>
    <xsl:param name="tolerance" as="xs:double"/>
    <xsl:choose>
      <xsl:when test="abs($n1 - $n2) &lt;= $tolerance">
        <xsl:value-of select="true()"/>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="false()"/>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:function>

<!-- item() compare -->
<xsl:function name="d:item-cmp" as="xs:boolean">
  <xsl:param name="n1" as="item()"/>
  <xsl:param name="n2" as="item()"/>
 <xsl:choose>
      <xsl:when test="$n1 = $n2">
        <xsl:value-of select="true()"/>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="false()"/>
      </xsl:otherwise>
    </xsl:choose>
</xsl:function>


<!-- Numeric compare (int, real, double etc.  -->
<!-- Convert to double -->

 <xsl:function name="d:numeric-cmp" as="xs:boolean">
    <xsl:param name="n1" as="xs:double"/>
    <xsl:param name="n2" as="xs:integer"/>
    <xsl:param name="tolerance" as="xs:double"/>
    <xsl:variable name="n2d" select="number($n2)" as="xs:double"/>

    <xsl:choose>
      <xsl:when test="abs($n1 - $n2d) &lt;= $tolerance">
        <xsl:value-of select="true()"/>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="false()"/>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:function>


I'm unsure on the last one.
I want to take 'any' numeric format and convert to double
prior to testing.
