 LINKSETS
 ======================================================
 Child prims do not report collisions
+Allow children of a linkset to be phantom:
+	http://opensim-dev.2196679.n2.nabble.com/Setting-a-single-child-prim-to-Phantom-tp7578513.html
+	Add OS_STATUS_PHANTOM_PRIM to llSetLinkPrimitaveParamsFast.
 Editing a child of a linkset causes the child to go phantom
 	Move a child prim once when it is physical and can never move it again without it going phantom
 Offset the center of the linkset to be the geometric center of all the prims
