Example of DOM transformations operated by XWiki is setting the right target of links that have rel="external" attribute so that the document can be XHTML valid and still have the desired effect, making internal rendering error messages expandable, insert document template handlers for links to non-existent documents, and so on. In the future there might be more transformations operated by XWiki upon DOM initialization. This event is meant for code to be notified of loading of the XWiki-transformed version of the initial DOM. As ##dom:loaded##, it can be used as follow:
