ulink.show
— Display URLs after ulinks?
If non-zero, the URL of each ulink will
appear after the text of the link. If the text of the link and the URL
are identical, the URL is suppressed.
See also ulink.footnotes.
DocBook 5 does not have an ulink element. When processing
DocBoook 5 documents, ulink.show applies to all inline
elements that are marked up with xlink:href attributes
that point to external resources.
