- Type: space separated list of datasource URIs
- A space-separated list of datasources that an element's template will use for content generation. These can be either internal datasources such as rdf:bookmarks or a URL. The datasources attribute may be placed on most elements, although it will usually be found on trees and menu related elements. The element should have a
template element as a child.
- For RDF templates, the specified datasources are combined into a single composite datasource which holds the data from all of the datasources. This composite datasource is accesssible via a script through the database property.
- For XML datasources, only one source is used, either the URL of an XML file or an anchor reference to another element within the same document. For instance, the reference '#data' refers to an element with the id 'data'.
- If you plan on adding a datasource to an element but don't want one to be added right away, set this attribute to 'rdf:null'. This will make the element so that its contents can be generated from a datasource. Otherwise, you cannot add one later.
- When the XUL document is contained on a remote web site, the datasources may only be loaded from the same domain as the document.
