Have you read the FAQ (follow the link at the bottom of this mail) on
sorting and grouping?

The "//" at the beginning of the first two expressions is inefficient but
not incorrect. In the <xsl:sort> it is disastrous: it means that instead of
selecting the Merchant part of each GetMerchantListResponse, you are using
the first Merchant in the data as the sort key for each record. 

In any case, Merchant seems an odd choice of sort key as it is a composite
value. Your narrative suggests that you want <xsl:sort
select="Merchant/merchIsoId"/>
