<para>
If true, bibliography entries which are not cited are suppressed.
A biblioentry is cited if an XREF or LINK matches its ID, or if
a CITE element matches its
ID, XREFLABEL, or leading ABBREV.
</para>
<para>
A BIBLIOGRAPHY with no entries will still be output (making a whole
component conditional would be _A LOT_ of work and seems unnecessary),
but BIBLIDIVs with no entries will be suppressed.
</para>
<para>
This setting may have significant performance implications,
hence it is false by default.
</para>
<para>
(This option can conveniently be set with <literal>-V biblio-filter-used</literal> on the 
Jade command line).</para>
