The API allows for FileAttributeViews to be defined beyond the 
specification (ie: you aren't limited to those that are defined by the 
java.nio.attribute package). To that end, we expect to include an 
implementation specific FileAttributeView that provides access to all 
the file type bits in the file mode. The uid/gid would also be 
accessible, as would other stat members (you almost have the uid/gid 
already with the UserPrincipal abstraction).
