dir permissions: delete enclosed files but not create or write to files

I want the following situation for a user's directory: - user can list files - user can read files - user can delete files - user cannot add files - (ideally, also) user cannot modify files I haven't been able to think of a way to do this with permissions and xattrs. Any thoughts? The file system types in use are NFS v3 and GPFS. The OS is RHEL 7 Linux.
