each inline element can also serve as a simple XLink
it is necessary to declare XLink namespace:
<article xmlns="http://docbook.org/ns/docbook" xmlns:xl="http://www.w3.org/1999/xlink" version="5.0"> <title>Test article</title> <para><application xl:href="http://www.gnu.org/software/emacs/emacs.html">Emacs</application> is my favorite text editor.</para> …
ulink
was removed in favor of ubiquitous
linking:
<link xl:href="http://docbook.org">DocBook site</link>
XLink with fragment identifier can be used for cross-references inside one document
<command linkend="dir">DIR</command> <command xl:href="#dir">DIR</command>
difference is in validation—linkend
is checked during validation for
ID/IDREF consistency
XLink is not checked—can be useful for XInclude based modular documents
