dsssl functions

[Boris Goldowsky <boris@xxxxxxxxxxxx>]

A couple of questions.  I know scheme and SGML pretty well, but am new
to DSSSL.

1. Does someone have a quick-reference list of functions legal in
   DSSSL, or just the DSSSL stylesheet language, or Jade?
   I'm looking for a reference source shorter than the text of the standard.

2. Many DSSSL functions accept arguments in keyword/value pairs -- 
   as in (make element GI: "P" attributes '(...)).
   I'm familiar with defining functions in scheme, but how do you
   define a function with keyword arguments like that?

3. Are there resources somewhere which give some comparisons of the
   various DSSSL engines that are available?  What do you get for your
   money if you buy one of the commercial ones?
