I had the same problem with parsing a list of indeterminate length, and the
solution was to use a call-template in a recursive fashion. Here is a
stylesheet that should work (I ran this with XT19990813)

<xsl:stylesheet xmlns:xsl="http://www.w3.org/XSL/Transform/1.0">

<xsl:template match="/">
  <result>
  <xsl:call-template name="recurse">
    <xsl:with-param name="parse-string">
      thing1; thing2; thing3; thing4
    </xsl:with-param>
  </xsl:call-template>
  </result>
</xsl:template>

<xsl:template name="recurse">
  <xsl:param name="parse-string"></xsl:param>
  <xsl:if test="not($parse-string='')">
    <field>
      <xsl:choose>
      <xsl:when test="contains($parse-string, ';')">
        <xsl:value-of select="substring-before($parse-string, ';')"/>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="$parse-string"/>
      </xsl:otherwise>
      </xsl:choose>
    </field>
    <xsl:call-template name="recurse">
      <xsl:with-param name="parse-string">
        <xsl:value-of select="substring-after($parse-string, ';')"/>
      </xsl:with-param>
    </xsl:call-template>
  </xsl:if>
</xsl:template>

</xsl:stylesheet>
