Bug 299536 API refers to non-API type UIResourceFilterDescription
I20100112 CreateGroupOperation and CreateFolderOperation have constructors that require a UIResourceFilterDescription[].

Either the constructor should be removed or something like UIResourceFilterDescription needs to be promoted to API. Also, shouldn't CreateFolderOperation be renamed CreateVirtualFolderOperation?
