For the below question, I got the answers from you
using <xsl:for-each-group>. But my version of XSLT is
not supporting xsl:for-each-group.
Then it must be XSLT 1.0.
Is there a different way of implementing this?
Please find an XSLT 1.0 solution below that generates the
output you specify.
I hope this helps.

p.s. Which order/order-response vocabularies are you
using? Have you considered using the OASIS Universal
Business Language (UBL) for such business documents?
