Hi Jirka,
I just tried it with xsltproc, and it fails with
this message (repeated several times):

xmlXPathCompOpEval: function group-index bound to undefined prefix i

This seems odd, since the XSL file includes this namespace
declaration in the root element:

  xmlns:i="urn:cz-kosek:functions:index"

I even tried adding the namespace declaration here:

  <func:function name="i:group-index"
                 xmlns:i="urn:cz-kosek:functions:index">

and I still get the same error.  I wonder if this
is a bug in xsltproc's implementation of
exslt functions?
