+[NOTE]
+The RPC descriptor just described is the first buffer in the
+OST_SETATTR request message. It will also appear as the first buffer
+of every other RPC request or reply sent between entities. Refer back
+to the above discussion when examining other RPC messages. The next
+section describes the 'struct ost_body' which is the second (and
+final) buffer in an OST_SETATTR request message.

include::struct_ost_body.txt[]
+The above discussion described the structure of the OST_SETATTR
+request message. In this case the reply message sturcture looks much
+the same. It uses the same to buffers, and oly changes their contents
+to reflect that the message is a reply rather than a requsest.
