<refpurpose>Collects information for potential cross reference targets</refpurpose>

<refdescription id="collect.targets-desc">

<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.
