FWIW, P is the styling language of Amaya because it is the one of
ThotLib, you may want to mention this.

To customize a stylesheet in DSSSL, you'll need an example with much
more context, including the SGML tags that enclose the scheme-based
code:

========== cut here
<!DOCTYPE style-sheet PUBLIC "-//James Clark//DTD DSSSL Style Sheet//EN" [
<!ENTITY parentdsl PUBLIC "Public//identifier//of//parent//stylesheet" CDATA dsssl>
]>
<style-sheet>
  <style-specification use="parent">
    <style-specification-body> 

;; your overrides go here

(element H1
  (make paragraph
      font-size: (* 2 (inherited-font-size))))

    </style-specification-body>
  </style-specification>

  <external-specification id="parent" document="parentdsl">
</style-sheet>
========== cut here

I'm not 100% sure, but I believe that it is also possible in P,
although I have to check.  I also believe the code for generated text
is overly complicated - I see if I find some time to make better.

The "Select any P element that is the first child element of its
parent" code for DSSSL has been pasted twice.

HTH,
