     <!-- TODO: is hard coding an OID going to be a problem? -->
+
+<!-- 
+     Per https://wiki.evolveum.com/display/midPoint/Object+ID
+     OIDs can be set to anything as long as they are unique across the entire midpoint installation.
+
+     Trying to use a URN to avoid collisions between an institution's own stuff and TIER-provided configs
+     does work but...
+     
+     There is a passage about properly generating all OIDs using something like `uuid` but Tom & I read that
+     as avoiding semantically significant *numeric* OIDs. using something like a URN creates namespaces that
+     are seperated by the naming convention already.
+
+     Something to discuss...
