std.svg.xml

Interner XML-Schreiber der SVG-Bibliothek: Puffer-Management, Zahlenformatierung (f64 → kompakter SVG-String), Attribut-Escaping und Dokumentstruktur (XML-Deklaration, SVG-Namespace). Wird von allen anderen SVG-Units intern verwendet — direkte Nutzung ist nur für benutzerdefinierte SVG-Elemente nötig.
