we think the following interaction between HTML5 section "5.6 Offline Web applications" and XMLHttpRequest needs a clarification:


When doing a XMLHttpRequest GET request with a request URL which is for a host for which a cache host exists which has an application cache with completeness flag set to complete associated which contains  a master entry, an explicit entry or a fallback entry for the request URL, should the XMLHttpRequest get the entry from the cache or fetch the resource normally or fail with a network error? 


Use cases are eg dynamically loading javascript files or dynamically loading HTML files to use them in a DOM replacement operation which displays a smooth transition (eg jQuery Mobile does this if not instructed otherwise).


Browsers currently implement this differently.
