<!--
The stock collateindex.pl (md5=2e36626ed6709e5ba0e6af0999bc3102, in
dsssl-stylesheets-1.79) program makes a few mistakes in generating
the complex index below.
It creates a nesting problem for <secondaryie/> elements which contain
both a <ulink/> and have a subsequent <seeie/>. In that case, it
orphans the <ulink/> elements beneath the <seeie/> AFTER closing the
<secondaryie/>. I can't figure out the collateindex.pl patch, so
hand-fixed the 5 entries and am committing this as is for TLDP.

<!-- ULINK is abused here.
The URL attribute holds the URL that points from the index entry
back to the appropriate place in the output produced by the HTML
stylesheet. (It's much easier to calculate this URL in the first
pass.)
The Role attribute holds the ID (either real or manufactured) of
the corresponding INDEXTERM. This is used by the print backends
to produce page numbers.
The entries below are sorted and collated into the correct order.
Duplicates may be removed in the HTML backend, but in the print
backends, it is impossible to suppress duplicate pages or coalesce
sequences of pages into a range.
