Create an output XML file with namespaces from an input XML file without namespaces.

For that first WE need to use literals.Literals provide a way through which we can map XML_IN(without namespace) to XML_OUt(with namspace).

Following are the steps:
1.) Create Literals on input side. suppose String1 and String 2
2.) Map String 1 with name/xmlAttr
3.) MapString2 with value/xmlAttr
4.) Inside the link code of string1->name/xmlAttr, we need to mention the source expression like "xmlns:<>" same as according to XSD file.
5.) In same way , mention the source expression for string2->value/xmlAttr like "urn:segments" which is according to the XSD file

Source expression must be in double quotes.

Just create literals and map it to the name/value pair of xmlAttr record.
