For more details, see this document: http://dev.w3.org/html5/decision-policy/decision-policy.html Status: Rejected Change Description: No change Rationale: It sounds like you are asking for a new attribute, e.g., refresh="5s", that would only apply to replaced elements like iframes, since we don't want to allow arbitrary elements to load or replace their content from a URL. The use case sounds like it is for ads, which usually use JavaScript to request and update content from different URLs. Its not very typical to serve multiple unique documents from a single URL, as that would generally make the experience unpredictable. Adding a refresh attribute to an iframe would only request the same content, most likely from the cache, or if not, one would typically expect the same content from the server. Extrapolating from your idea, it sounds like this could be a request for an iframe source carousel, which is an interesting notion. However, the use cases seem fairly limited at this point.
