Document how file attributes are used by OneDrive Files On Demand
People developing applications and scripts that interact with files stored on OneDrive would benefit from understanding how to get/set the OneDrive status (online-only, locally available, always available) from code. This is currently almost completely undocumented. Reverse-engineering (see for instance https://social.technet.microsoft.com/Forums/windows/en-US/375f3933-fcab-450c-bb9c-da54155549e2/how-do-i-getset-onedrive-files-on-demand-status-from-powershell?forum=ITCG or https://superuser.com/questions/1214542/what-do-new-windows-8-10-attributes-mean-no-scrub-file-x-integrity-v-pinn/1287315) is not the way to go!
