All information that is entered into any of the XRPS web interfaces is, when pressing the ``commit'' button, stored in a memory. The commit button is always located at the bottom of the right frame of the web interface. From this memory entries can be loaded again later, as sketched in Fig. 5. This implies that XRPS users have no access to the proposal database itself.
Each user can have up to 20 proposals in memory that have not yet been submitted to the proposal database.
The submission procedure is described in § 5.9. Note that the list of proposals by each PI in the XRPS memory does not contain any information on whether a proposal has already been submitted or not (because the memory is just a working area, not a proposal submission database). Submission will only be acknowledged by email upon receipt of the submitted proposal in the primary database.
