Subject: sosofo-append or sequence? From: Tony Graham <tgraham@xxxxxxxxxxxxxxxx> Date: Wed, 6 May 1998 12:07:20 -0400 (EDT) |
This started from an off-line discussion with Chris Maden, but does anyone have an opinion, or a definitive rule, for when to use sosofo-append and when to use sequence? Chris's example in his "Basic footnotes" post yesterday was: (element sect1 (sosofo-append (process-children) (with-mode footnotes (process-children)))) This could just as easily have been: (element sect1 (make sequence (process-children) (with-mode footnotes (process-children)))) Is there are significant difference, or does it really not matter? A rationale for using sosofo-append would be that it results in a flatter flow object tree, but to what extent would that affect performance? Seemingly the only time that you need to use sequence instead of sosofo-append is when declaring characteristics to be inherited: (element sect1 (make sequence start-indent: 4pi (process-children) (with-mode footnotes (process-children)))) but is that true? Just a touch of DSSSL philosophising to brighten your day. Regards, Tony Graham ======================================================================= Tony Graham Mulberry Technologies, Inc.
