<!--
 - Pre-process the spec before handing it over to standard DocBook. This allows
 - using convenient shorthands that DocBook does not provide. Currently these
 - shorthands are:
 -
 - <defterm>term</defterm> is converted to an <indexterm>, using "term" as
 - the primary, with "preferred" significance. This is used to create a short
 - index of "important terms" as an - appendix.
 -
 - <refterm>term</refterm> is converted to an <indexterm>, using "term" as
 - the primary, with "normal" significance. This is used to add list of
 - usage points to each "important terms" in the appendix.
