Broaden the serializer and writer options from the audit: - attributeQuote selects single or double quotes; the active quote is escaped in values (apostrophe as ' in single-quote mode). - lineEnding controls the inserted newline (set to CRLF for \r\n output). - xml:space=preserve suppresses pretty-print indentation for an element and its subtree; xml:space=default re-enables it. - Writer gains writeStartElementNS(prefix:localName:namespaceURI:) and writeNamespace(prefix:uri:), so callers no longer hand-format prefixes and xmlns attributes. CDATA-vs-escape and entity re-escaping strategies are left as a follow-up; the current escaping is the safe default. Closes #91
