RE: [xsl] last() and distinct-values 2.0

[Jurn Ho <jurn@xxxxxxxxxxxxxxxx>]

Hi Michael,

Thanks for that. I tried your suggested workaround and everything is great.

I was playing with namespaces before because I was wondering why the 
distinct-nodes function wasn't found (I realise now it only existed in a 
draft 2.0 spec).

glad I could help bug hunting.

cya,
Jurn
