Not really. The most common use may be that, but xsl can convert an
XML document to pretty much any format you want and can even convert
between compatible encodings. (You would lose something to try to
convert from Chinese to Latin1, obviously, but you should be able to
convert from Latin1 to UTF-8 or from UTF-8 to UTF-16 if desired.) It
is even possible to go from XML to PDF. (I haven't tried it, so I
don't know how well it works.)

Exactly. The input XML document and the XSL stylesheet must both be
valid XML, but the output can be just about anything you want.  You
could have an XML table definition and use XSL to translate that
structure into a valid SQL statements using that table in a specific
SQL vendor dialect. Those could be anything as simple as generating
CREATE TABLE statements to build a script to create a database or as
complex as building stored procedures against those tables.
