Differences between XSL and DSSSL

I know that XSL and DSSSL have a different focus and i learned that DSSSL is likely to be extended to be a superset of XSL.
What is it that makes XSL a true subset of DSSSL?
Is there a paper/site that lists the differences between XSL and DSSSL like http://www.w3.org/TR/NOTE-sgml-xml-971215.html does with SGML and XML?

Best regards,
Florian.
