Re: current() - referring to top in nested predicates

The following produces empty output and hence doesn't work, but you
probably can see my intention. Using the current() function, I'm trying
to refer to the current <T> to find out if the current <B> contained in
$b falls within the bounds of the interval, but without success.

<xsl:transform version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="text"/>
  <xsl:variable name="b" select="//B"/>
  <xsl:template match="/">
    <xsl:apply-templates select="//T [ position() != last() ]"/>
  </xsl:template>
  <xsl:template match="T">
    <xsl:if test="count( $b[.  >=  current() and
                      . &lt; current()/following-sibling::T[1]]) > 0">
      <xsl:value-of select="."/>
      <xsl:text>&#10;</xsl:text>
    </xsl:if>
  </xsl:template>
</xsl:transform>
