Re: xsl namespace problem

A couple things:

match="aco:/GetProductOptionsResponse

can't work. You need

match="/aco:GetProductOptionsResponse

Then, in the XML document, replace

<GetProductOptionsResponse xmlns="http://www.accovia/TRIP2004A/01">

with

<GetProductOptionsResponse xmlns:aco="http://www.accovia/TRIP2004A/01">

Also, your two URLs, http://www.org/TRIP2004A/01 and 
http://www.accovia/TRIP2004A/01, don't match.
