Instead of trying to implement the full set of wiki markup commands of systems like MediaWiki, XoWiki is based on a rich text editor and focuses more on integration with oacs (e.g categories, general comments, adp-includes). XoWiki combines aspects of wikis (ease of page-creation) with aspects of a content management system (revisions, reusable content, multiple languages). Furthermore, XoWiki allows to define different types of links such one could define book-structures (where a navigation structure could be built on the fly) or glossaries with differnt kind of word relationships (like synonyms, etc.). XoWiki supports pages in multiple languages and is localized (currently only for English and German).

In the same step, i have replaced in my oacs 5.2b5 revision
RTE with xinha, which is much nicer. If there is interest, i can provide patches or import the changed files (and/or xowiki) into CVS.
When i upgraded to the selva theme, i noticed that the contents of the title variable is not displayed on the pages. Is this intended?
