    abstract =  {This document presents necessary clarifications and corrections concerning features related to the use of attributes in NFSv4.1 related to file system location. These features include migration, which transfers responsibility for a file system from one server to another, and facilities to support trunking by allowing discovery of the set of network addresses to use to access a file system. This document updates RFC5661.},
