Results from XSLT processors I have on my machine:

  Output                XSLT Processor
  92125374252539904000  SAXON 6.1
                        Xalan-C 1.0

Interesting. Which, if any, is actually right?

Just a desperate attempt to write a readable question :) BTW, would SAXON
optimize e.g.

  <xsl:value-of select="number(string('42'))" />


  <xsl:value-of select="42" />

during stylesheet preparation? And even though no one would ever write
something like

  <xsl:if test="foo[boolean(contains(., 'get something better to read')) =

would it be optimized somehow before executing the stylesheet to

  <xsl:if test="foo[contains(., 'get something better to read')]">

or something in those lines? Just curious ;)
