XWiki supports 16+ input syntaxes (e.g. confluence, twiki, docbook, mediawiki, xwiki, markdown, etc), see http://rendering.xwiki.org/xwiki/bin/view/Main/WebHome#HSupportedSyntaxes for details.

The syntax documented below is XWiki Syntax 2.1 (http://platform.xwiki.org/xwiki/bin/view/Main/XWikiSyntax).
