  Hello,

  do you know the dark corners of XSLT? Here is one. Compare two
variables:

<xsl:variable name="v1" select="some-xpath"/>
<xsl:variable name="v2"><xsl:copy-of select="some-xpath"/></xsl:variable>

  Are "v1" and "v2" the same? I mean: can "v1" and "v2" be used in a
program interchangeably? Answers:

1) yes
2) no
3) implementation-dependant

  The right answer is (2): no. Changing a use of "v1" to "v2", or reverse,
might change the result of a stylesheet. I'll post an example later. Or
you can provide your version.
