[graap-wg] Access to "Definition of Advance Reservation" Document

Hi, I'm trying to access the link for 'the definition of advance reservation' [1] from the GRAAP-WG GridForge project summary. When I try to do so, I get the following error: "DCMN-000073: The requested document Advance-Reservation-Definition- htm resides in a hidden category. Permission denied". Is this definition publicly available, or a configuration error on the website? Thanks, Michael.
