Fragment serialization should always use 'xml:' prefix for attributes in XML namespace: - https://html.spec.whatwg.org/#serialising-html-fragments """ If the attribute is in the XML namespace -> The attribute's serialized name is the string "xml:" followed by the attribute's local name. """ - https://www.w3.org/TR/DOM-Parsing/#dfn-concept-xml-serialization-algorithm """ If ns is the XML namespace, then let qualified name be the concatenation of the string "xml:" and the value of node's localName. """
Firefox complies with the specification.
