RFC 3576 does not use attributes in the CoA-Request in order to request
attributes in a subsequent Access-Request. Nor does it make sense to
include location attributes in a CoA-Request. The session to which the
CoA applies is not selected using location attributes, nor is the request
that the NAS change its location -- "Please move NAS17483 to Cleveland,

See RFC 3576 Error-Cause attribute, value 402 (Missing Attribute)

I was confused about this as well.

I don't understand this either.
