1.  Introduction

   This document provides the External Data Representation Standard
   (XDR) description for Network File System version 4 (NFSv4) minor
   version 1.

1.1.  Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [1].

1.2.  Code Components Licensing Notice

   The XDR description and scripts for extracting the XDR description
   are Code Components as described in Section 4 of "Legal Provisions
   Relating to IETF Documents" [2].

2.  XDR Description of NFSv4.1

   This document contains the XDR ([3]) description of NFSv4.1 protocol
   ([4]).  In order to facilitate implementations that support both
   NFSv4.0 and NFSv4.1, the description includes operations and other
   features of NFSv4.0 that do not apply to NFSv4.1.

   The XDR description is provided in this document in a way that makes
   it simple for the reader to extract into ready-to-compile form.  The
   reader can feed this document in the following shell script to
   produce the machine readable XDR description of NFSv4.1:

   #!/bin/sh
   grep '^ *///' | sed 's?^ */// ??' | sed 's?^ *///$??'

   <CODE ENDS>

   That is, if the above script is stored in a file called "extract.sh",
   and this document is in a file called "spec.txt", then the reader can
   do:

   <CODE BEGINS>

    sh extract.sh < spec.txt > nfs4_prot.x

   <CODE ENDS>
