[Bari, Farooq] I meant the first of the two. If others have
the same
understanding we can change it to "selection of the
realm used to access
the network".

[Bari, Farooq] I do not think RFC 4284 mandated a behavior
on the part
of the network that would imply that the client always gets
the entire
list of roaming partners of the e.g. the hotspot operator.
For example
it is possible that hotspot operator decides to advertise
only top three
roaming partners etc. But such logic is not something that
gets
standardized.
