Re: sum of the evaluated values

Or you could even implement "+" on your time type:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:func-transform="f:func-transform"
exclude-result-prefixes="xsl func-transform"
>
   <xsl:import href="transform-and-sum.xsl"/>

   <xsl:output method="text"/>
   
   <func-transform:func-transform/>

    <xsl:template match="/">
      <xsl:variable name="sumSeconds">
          <xsl:call-template name="transform-and-sum">
            <xsl:with-param name="pFuncTransform"
                            select="document('')/*/func-transform:*[1]"/>
            <xsl:with-param name="pList" select="/*/*/@time"/>
          </xsl:call-template>
      </xsl:variable>
      
      <xsl:value-of
          select="concat(floor($sumSeconds div 60),
                         ':',
                         $sumSeconds mod 60
                                   )"/>
    </xsl:template>
    
    <xsl:template match="func-transform:*">
      <xsl:param name="arg" select="0"/>
      <xsl:value-of select="substring-before($arg, ':') * 60 
                          + substring-after($arg, ':')"/>
    </xsl:template>

</xsl:stylesheet>

which when applied on the following xml document:

<events>
  <event type="1" time="3:15"/>
  <event type="0" time="2:28"/>
  <event type="1" time="4:22"/>
  <event type="1" time="5:11"/>
</events>

Gives the following result:

15:16
