/**
 * JsonToXml — JSON → XML conversion
 * ────────────────────────────────────
 * Converts a plain JavaScript object (JSON-serialisable) into an XmlDocument
 * or an XML string.
 *
 * Conversion rules
 * ────────────────
 *  • Object keys become element tag names
 *  • Keys with the configured attribute prefix become attributes
 *  • The configured text key becomes a text node
 *  • Array values produce repeated sibling elements
 *  • Primitive values (string / number / boolean) become text nodes
 *  • null values produce an empty self-closing element
 *
 * Usage
 * ─────
 *  import { jsonToXml, jsonToXmlString } from 'xml-xsd-engine/transform';
 *
 *  const doc = jsonToXml({ root: { '@id': '1', name: 'Alice' } });
 *  // → <root id="1"><name>Alice</name></root>
 *
 *  const xml = jsonToXmlString({ root: { item: ['a', 'b', 'c'] } });
