OIC-3 XSLT expression to dynamically assign value to the element

Summary: OIC-3 XSLT expression to dynamically assign value to the element

I have a use case where the downstream application uses a standard XSD for AR Invoice outbound. The values of each attribute differs based on country as per compliance requirement. Most of the fields are common in most cases (almost 80%). The remaining fields either fall under following categories,

1. Assign constant value (e.g. transmission code/ tax code to specific hard coded value)
2. Expression similar to decode (e.g. DECODE(SrcField1, VALUE1, OUTPUT1, OUTPUT2) or DECODE(SrcField1, VALUE1, SrcFieldA, SrcFieldB) and so on)
