> Several read/write options are registered in the JSON and XML data sources but are absent from the option tables in the documentation.
> This adds rows for the JSON options pretty and writeNonAsciiCharacterAsCodePoint, and the XML options indent, multiLine, prefersDecimal and preferDate. Each default and description is taken from source: for example indent defaults to XmlOptions.DEFAULT_INDENT (four spaces), multiLine defaults to true for XML, and preferDate is disabled when spark.sql.legacy.timeParserPolicy is set to LEGACY.
> The gap was found by diffing the newOption registrations in JSONOptions and XmlOptions against the documented option names. After this change the JSON table is complete; the XML table still omits useLegacyXMLParser, a legacy parser-implementation switch, which is left undocumented on purpose.
> Documentation only.
