Sgml2x allows to easily format SGML and XML documents using DSSSL stylesheets, and provides the following features: * Multiple possible stylesheets per document class * Easy specification of style-sheets using sort aliases * Easy integration of new stylesheets by adding a simple new definition file in a configuration directory * The caller can specify a PATH-like list of configuration directories, defaulting to one system-wide, one per-user, and one per-project configuration directory * Automatic selection of a default stylesheet to be used

It will currently be most useful with one of the suggested sets of DSSSL stylesheets for DocBook.
