A facility for rendering a dynamic electronic document is described. The dynamic electronic document has both a current and a future edition. The current edition incorporates a current version of a content item, while the future edition incorporates a future version of the content item. The facility receives a request to return the dynamic electronic document. In response to the request, the facility retrieves a template for the electronic document that contains a single identifier that identifies a group of content item versions containing both the current version of the content item and the future version of the content item. The facility uses the single identifier contained in the template, together with an indication of whether the current edition of the dynamic electronic document or the future version is being requested by the received request, to incorporate the appropriate version of the content item in the rendered dynamic electronic document.
