* XAttr is the POSIX Extended Attribute model similar to that found in

* 1) USER namespace attributes may be used by any user to store

* only the owner and privileged user can write attributes.
* <br>
* 2) TRUSTED namespace attributes are only visible and accessible to
* privileged users. This namespace is available from both user space
* (filesystem API) and fs kernel.
* <br>
* 3) SYSTEM namespace attributes are used by the fs kernel to store
* system objects. This namespace is only available in the fs
* kernel. It is not visible to users.
* <br>
* 4) SECURITY namespace attributes are used by the fs kernel for
* security features. It is not visible to users.

* sometimes need to be exposed. Like SYSTEM namespace attributes they are
* not visible to the user except when getXAttr/getXAttrs is called on a file
