Обсуждение: duplicated index entry found ...

Non-critical, but figured I'd mention it ... this was from the beta build
this evening ...

/usr/local/bin/perl /usr/local/share/sgml/docbook/dsssl/modular/bin/collateindex.pl -f -g -i 'bookindex' -o
bookindex.sgmlHTML.index

4 entries ignored...
Done.

Yeah, I've been seeing that for quite some time, but haven't been able
to figure out what it's complaining about.  Surely multiple index
entries for the same term are legal, so what's its beef?

Since by default (which we don't override) an index entry points to its
nearest containing section (rather than directly to its occurence), if a
section contains the same index entry more than once, it does indeed look
like a duplicate on the outside.  There are at least two obvious ways to
get rid of the warnings, but I could never figure out the benefits and
drawbacks of them.
