[xslt] exslt function supported by xsltproc

[=?iso-8859-15?q?Fr=E9d=E9ric=20Laurent?= <fl opikanoba org>]

hello

According to the exslt website [1], the power function (math module) is
available in libxslt

Moreover if I make a test :

 xsltproc --dumpextensions
Registered XSLT Extensions
--------------------------
Registered Extension Functions:
{http://exslt.org/math}lowest
{http://exslt.org/math}constant
{http://exslt.org/math}power
...

So, I've got power :-)

Then, with a very simple test like this :

-------------- 8< ------- testpower.xsl  -------------------------------------
<xsl:stylesheet version="1.0"
          xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
          xmlns:math="http://exslt.org/math";
          extension-element-prefixes="math">

<xsl:template match="/">
  <result>
    <xsl:call-template name="math:power">
      <xsl:with-param name="base" select="5" />
      <xsl:with-param name="power" select="2" />
    </xsl:call-template>
  </result>
</xsl:template>

</xsl:stylesheet>
-------------- 8< ------------------------------------------------------------

and a foo.xml
<root/>

I try to run and 

xsltproc testpower.xsl foo.xml
runtime error: file testpower.xsl line 8 element call-template
xsl:call-template : template power not found
no result for foo.xml
