// Title: XML serialization of barcode settings via a web‑API style console demo
// Description: Demonstrates deserializing barcode configuration from JSON, generating a barcode, and exporting its settings to XML.
// Prompt: Integrate XML serialization of barcode settings into a web API that accepts configuration JSON and returns XML.
