Z3986 Requirements Detail

Indentation or empty lines are normally used in printed text to express paragraphs. A combination of both ways is also possible. In the latter case the empty line represents a new greater section and indentations represent the various paragraphs within that section. Note that there are other ways too to represent greater sections, such as a centered asterisk. When transferring text to DTBook the above described use of indentations and empty lines to express paragraphs and greater sections has no current standardised markup.

The obvious application of such a standardised markup would be within braille production, in which fidelity to the structure of the original text is of great interest, but also in any other output media from DTBook text.
