Next release XXE V2.9 will *not* include DocBook 4.4. > To use DocBook 4.4 with XXE, you need to modify the DTD to add xml:space > 'preserve' as a default attribute on "linespecific" elements, i.e. > literallayout, programlisting, programlistingco, screen, screenco and > screenshot.

Starting from XXE V2.9 (in principle, to be released next monday), this will not be an issue. Excerpts of *NOT YET RELEASED* V2.9 changes.html: --- The new "preserveSpace" configuration element allows to specify which elements are whitespace-preserving. For example, this configuration element is used in the DocBook, Simplified DocBook and Slides configuration files to specify that elements such as "programlisting", "screen", etc, are whitespace-preserving. Thanks to the new "preserveSpace" configuration element, the DocBook, Simplified DocBook and Slides DTDs bundled with XXE no longer need to be modified by XMLmind. Previously, these DTDs were modified in order to add attribute "xml:space" with default value "preserve" to elements such as "programlisting", "screen", etc. --- > Of course, you also need to modify catalog.xml and docbook.xxe, or > extend them in your user config directory. True. Thanks for the tip.
