the error message
'error message undefined template'

is telling you that the XSLT processor does not support this EXSLT
function natively, either

a) choose an XSLT Processor that natively supports this EXSLT function
(saxon and xalan do)

or

b) import the native XSLT implementation found at
http://www.exslt.org/set/functions/distinct/set.distinct.template.xsl
