I see nothing wrong with your template and indeed whan I run it as

<xsl:template match="/">
   <xsl:call-template name="tokenize.path">
       <xsl:with-param name="string" select="'input/xml/../'"/>
       <xsl:with-param name="delimiter" select="'/'"/>
   </xsl:call-template>
</xsl:template>


$ saxon delim.xsl delim.xsl
<?xml version="1.0" encoding="utf-8"?><token>input</token><token>xml</token><token>..</token>

which is, I think, the answer you wanted.
