STX is an XML transformation tool based on XSLT and Scheme
which combines a processor for most common XSLT stylesheets and a framework for
their extension in Scheme and provides an environment for a general-purpose
transformation of XML data.
It integrates two functional languages - Scheme and
XSLT-like transformation language on the basis of the common data model - SXML.
