XML output by using XSL

HI All,

We have a requirement in XML output, we need to display below content in the header. We are getting first line in the output. Please suggest how to achieve second line in the XML output by using XSL.

<?xml version = '1.0' encoding = 'UTF-8'?>

ns1:Sales_Inbound_Client xmlns:b="http://schemas.microsoft.com/BizTalk.2003" xmlns:ns1="http://Test.Xyz.ca/XMLClientRequest"

Thanks,

Visu
