You can force inclusion of formats that are not actually used in the body content of the source, such as those employed only for headers and footers. For example:
[Required]
; format name = format type, block or inline
Author = block
Header = block
Footer = block
For HTML output, this forces inclusion of formats that are not defined in the source file, such as those used in macros. Because content in these formats is added at the end of processing, formats listed here cannot contribute any before, after, start, or end content to HTML output.
For RTF output, if you do not specify a format type the correct properties are still used, but they appear as overrides to format Normal.
