olink.doctitle — show the document title for external olinks?
When olinks between documents are resolved, the generated text may not make it clear that the reference is to another document. It is possible for the stylesheets to append the other document's title to external olinks. For this to happen, two parameters must be set.
This olink.doctitle parameter
should be set to either yes or maybe
to enable this feature.
And you should also set the current.docid
parameter to the document id for the document currently
being processed for output.
Then if an olink's targetdoc id differs from
the current.docid value, the stylesheet knows
that it is a reference to another document and can
append the target document's
title to the generated olink text.
The text for the target document's title is copied from the
olink database from the ttl element
of the top-level div for that document.
If that ttl element is missing or empty,
no title is output.
The supported values for olink.doctitle are:
yesAlways insert the title to the target document if it is not the current document.
no
Never insert the title to the target document, even if requested
in an xrefstyle attribute.
maybe
Only insert the title to the target document, if requested
in an xrefstyle attribute.
An xrefstyle attribute
may override the global setting for individual olinks.
The following values are supported in an
xrefstyle
attribute using the select: syntax:
docname
Insert the target document name for this olink using the
docname gentext template, but only
if the value of olink.doctitle
is not no.
docnamelong
Insert the target document name for this olink using the
docnamelong gentext template, but only
if the value of olink.doctitle
is not no.
nodocname
Omit the target document name even if
the value of olink.doctitle
is yes.
Another way of inserting the target document name
for a single olink is to employ an
xrefstyle
attribute using the template: syntax.
The %o placeholder (the letter o, not zero)
in such a template
will be filled in with the target document's title when it is processed.
This will occur regardless of
the value of olink.doctitle.
Note that prior to version 1.66 of the XSL stylesheets, the allowed values for this parameter were 0 and 1. Those values are still supported and mapped to 'no' and 'yes', respectively.
