RE: AuthenticatorLocale Definition

[Irving Reid <Irving.Reid@baltimore.com>]

Does the AuthenticatorLocale trace back to any specific requirements?
Core-0.15 says that it's optional, since the information can be spoofed;
given that, I think we need more rationale for why it's in the spec at all.

If we want a way to record the source IP address from which an
authentication originated (for example, to protect against interception of
authentication assertions), the SubjectConfirmation field seems more
appropriate. Then the logic would be: the way you confirm that the presenter
of this assertion is the subject is that the message came from the
corresponding IP address.
