Re: modular docbook stylesheets speedup tips?

[Norman Walsh <norm@xxxxxxxxxxxxx>]

/ ssb@xxxxxxxxxxx (Stig S. Bakken) was heard to say:

| takes almost _10 minutes_ for Jade to process my document.

I've found one possible problem.  The code in common/dbtable.dsl
uses the horrifying construction

  ... (descendants (sgml-root-element)) ...

to locate COLSPEC and SPANSPEC elements.  For a large document,
this is _SLOW_.  Change this instead to

  ... (descendants tgroup) ...

in both places and I'll bet things get a lot faster.  (Send me
reports, please, good or bad.)
  
Why did I do this?  Because the CALS Table spec says that
COLSPEC and SPANSPEC are inherited from _preceding_ tables. So
the stylesheet attempts to find all of them.  

Clearly this shouldn't be done the way I've done it.  So that
aspect of the CALS semantics will go away in the next stylesheet
release.  If you want to use COLSPEC and SPANSPEC, put them in
each TGROUP.
