ISO/IEC TR 19758:2003 provides a DSSSL (ISO/IEC 10179:1996) library that makes it feasible to describe DSSSL specification for documents described by SGML (ISO 8879:1986) or XML (Extensible Markup Language).

The library can deal with some complex compositions programmed by a number of complicated DSSSL specification statements. Those compositions consist of the formatting objects: paper size, paper placement, unit, basic composition style, font, character size, headline, page number, note, inlinenote, emphasizing mark, superscript/subscript, word-length adjustment, character space adjustment, clause, list, table, heading, ruby, paragraph indentation, score, rule, and inline.

The DSSSL library contains the simple parameter data and the four files:

• full parameter generator;
• function set;
• page model set;
• flow object construction rules.

Their actual data are specified in ISO/IEC TR 19758:2003.
