XSLT 1.0 to split CamelCase into words

What is the best practice for unit-test names? CamelCase or underscore or mixed or...? Good question. But you can side step it somehow. Here is the code I use for transforming unit-test names as displayed in CI server reports e.g. OrdersWithNoProductsShouldFail -> orders with no products should fail:

<xsl:template name="SplitCamelCase">
  <xsl:param name="text" />
  <xsl:param name="digitsMode" select="0" />
  <xsl:variable name="upper">ABCDEFGHIJKLMNOPQRSTUVWXYZ</xsl:variable>
  <xsl:variable name="lower">abcdefghijklmnopqrstuvwxyz</xsl:variable>
  <xsl:variable name="digits">0123456789</xsl:variable>
 
  <xsl:if test="$text != ''">
    <xsl:variable name="letter" select="substring($text, 1, 1)" />
    <xsl:choose>
      <xsl:when test="contains($upper, $letter)">
        <xsl:text> </xsl:text>
        <xsl:value-of select="translate($letter, $upper, $lower)" />
      </xsl:when>
      <xsl:when test="contains($digits, $letter)">
        <xsl:choose>
          <xsl:when test="$digitsMode != 1">
            <xsl:text> </xsl:text>
          </xsl:when>
        </xsl:choose>
        <xsl:value-of select="$letter" />
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="$letter"/>
      </xsl:otherwise>
    </xsl:choose>
    <xsl:call-template name="SplitCamelCase">
      <xsl:with-param name="text" select="substring-after($text, $letter)" />
      <xsl:with-param name="digitsMode" select="contains($digits, $letter)" />
    </xsl:call-template>
  </xsl:if>
</xsl:template>
