Portability must be included as part of a thoroughgoing review/rewrite of the section of eduPerson (200806) on "Identifier Concepts:"
1) uniqueness
2) persistence
2a) reassignable
3) mutable
3a) resynchable
4) palatable
5) opacity
6) correlatable
7) privacy
8) portable
Many of these properties need to have more possible values than True or False.
Here's a trial run with further revisions (dependency is indicated by indentation)

NOTE: Name identifiers are a threat to privacy to the extent that they are transparent, reversable, resynchable,
correlatable and portable
