All,

It is often useful to react to timed, possibly repeating, asynchronous
events. Use cases include:

o Auto-saving form data in the background at regular intervals.

o Doing polling for checking incoming email or chat messages.

o Doing polling for checking whether the currently edited document has
   been modified in the background by a third-party.

o Notifying a user that his session is about to expire or has expired
   (e.g. for banking).

o Bounding the time a user is allowed to fill-out a given form, for
   example with e-learning application, and automatically submitting
   the form and going to the next page after that delay has been
   reached.

I can see how a configurable xforms:timer element would perfectly fit
in the XForms philosophy, and I think that this should be built into
XForms.

In the meanwhile, have other implementors addressed this as an
extension?
