+<!--Description:This pares the generated sysdef down to just a set of items of the desired
+rank. In other words, you provide a list of IDs to keep and a system model
+rank (layer, package, collection, component). 
+Every item of that rank in the sysdef will be removed except those in the list
+of IDs.
+Primary use cases of this would be to extract a single layer, or to select a
+specific set of packages.
