Hi,
i have two schemas(xsds) . both source n target xsd's are same except their namespaces. As both having same element names, so i just want to copy all the elements of source to target.
but i want that they maintain there namespaces. When i'm using 'copy-of' function in xslt, target xml is taking namespace from source.
Is there any way to do it in xslt without mapping each n every element in jdev xslt designer as input xml is too large & it will be very tough to map everythg from designer.

Thanks,
Vinit
