for example a leafref to /ncs:devices/ncs:device/ncs:name presents the user with the list of devices but the user can actually put bogus data in reality if they chose.  is there a way to lock the entries received to the list presented.  is the only way to have an enum?      leaf device1 {                 type leafref {                     path "/ncs:devices/ncs:device/ncs:name";                 }                 mandatory true;                 // try with just ref to current                 must "/ncs:devices/ncs:device[ncs:name = current()]" {                     error-message "You must pick a valid device (just ref)";                 }             } i can enter bogus data although i am initially presented with my only options.  while it does not let me continue directly with the service i can hit enter at this point and continue on. admin@ncs% set services must_test test1 device1 lkjsdlk [ok][2016-03-24 16:25:41] admin@ncs% show services must_test test1 device1 lkjsdlk; ...
