Any elements appearing in the input document that are not named in the
configuration file are formatted using the values of the
*DEFAULT section. If the file contains no
*DEFAULT section, xmlformat uses
built-in default values.
If you want to see whether there are any elements in the document for
which you haven't specified any formatting options, run
xmlformat with the
--show-unconfigured-elements option. For example:
xmlformat --show-unconfigured-elements doc2.xmlThe following document elements were assigned no formatting options: title
As it happens, the title already formats in the desired fashion, so there's no necessity of adding anything more to the configuration file.
