Since version 0.2.7 you can use the xrefstyle attribute
like you would do with the DocBook Project stylesheets for HTML output.
Furthermore, you can also use olinks. Note that
Olinking is used in the PDF version of this manual,
in the section called “Change History”.
Actually, the common DocBook Project stylesheets version 1.72 are now used by dblatex to handle all of these features.
These features are fully described in the DocBook XSL: The Complete Guide book by Bob Stayton. In particular, the following sections cover these topics:
http://www.sagehill.net/docbookxsl/CustomXrefs.html explains how to use xrefstyle.
http://www.sagehill.net/docbookxsl/Olinking.html explains how to use olinks.
Dblatex defines a template that can be applied through
the xrefstyle attribute to format an ulink. The template has
the following general form:
url[.{show|hide}][.{after|infoot}]
The principle is that the show and
hide parts override locally for this ulink the
ulink.show parameter,
and the after and
infoot parts override locally the
ulink.footnotes parameter.
When only one part is defined, only one setup is overriden, and the other setup depends on the corresponding global parameter.
See ulink.show to have several examples of use of the ulink xrefstyle template.
