scope:

Is designed to specify the processing of valid SGML documents. DSSSL defines the semantics, syntax, and processing model of two languages for the specification of document processing: a) the transformation language for transforming SGML documents marked up in accordance with one or more DTDs into other SGML documents marked up in accordance with other DTDs. The specification of this transformation process is fully defined by this international Standard. b) The style, where the result is achieved by applying a set of formatting characteristics to portions of the data, and the specification is, therefore, as precise as the application requires, leaving some formatting decisions, such as line-end and column-end decisions, to the composition and layout process.
