I just want to clearify this a little bit:

STX is an XML/SXML transformation tool which is based on SXML/Scheme
and is compatible with a limited subset of XSLT.

It uses SSAX for XML->SXML transformation (but doesn't require it for 
processing of SXML data).
STX uses SXPath and its extensions for pattern-matching and scripting,
its transformational engine is based on SXSLT's pre-order traversal.

The set of "SXSLT" functions is a part of SSAX-SXML project at 
ssax.sf.net (SXML-tree-trans.scm), but it is orthogonal to 
SSAX _parser_ itself.

SSAX's primary purpose is XML->SXML transformation, SXSLT functions
are intended for SXML->anything transformation.
However, SSAX is much more than DOM-like XML->SXML parser, and it can be 
integrated with SXSLT more tightly: XSLT-like transformation of XML streams
is a possible example.

With SXPath and others SXML tools, SSAX and SXSLT provide a solid XML-processing 
environment for Scheme.
