<para>Processing the root element in the
|
|
<literal role="mode">collect.targets</literal> mode produces
|
|
a set of target database elements that can be used by
|
|
the olink mechanism to resolve external cross references.
|
|
The collection process is controlled by the <literal>
|
|
collect.xref.targets</literal> parameter, which can be
|
|
<literal>yes</literal> to collect targets and process
|
|
the document for output, <literal>only</literal> to
|
|
only collect the targets, and <literal>no</literal>
|
|
(default) to not collect the targets and only process the document.

</para>
|
|
<para>
|
|
A <literal>targets.filename</literal> parameter must be
|
|
specified to receive the output if
|
|
<literal>collect.xref.targets</literal> is
|
|
set to <literal>yes</literal> so as to
|
|
redirect the target data to a file separate from the

document output.
