In posix ACL is no equivalent to Windows's "enable/disable delete" 
attribute. Generally, if user have write access to a directory he can 
delete/rename file even he is not an owner of file. The only way to 
prevent him from this is to set a sticky bit on a directory containing 
your files. It tells to Linux - "only the owner of file can 
delete/rename it". Access rights of others then depend on rwx/ ACL settings.
