Although submission was already a powerful feature of version 1.0 of XForms, there are a number of common use-cases that it was unable to support. For example, although it's easy for an XForms 1.0 form to request an RSS feed and to display the data with a repeat, it's not possible for the user to specify the feed location at run-time, perhaps by typing a URL into an input control, or selecting from a list.

XForms 1.1 has added a number of new features to submission to control the URL, request headers, location of returned data, and more, which together make it much easier to build forms that use servers based on REST, ATOM, SOAP, and WebDAV.
