/**

Connection preference to specify an access point to start. 

However, this preference cannot be used with RConnection::Start as a TConnPref. It

must be part of a TConnPrefList.

TConnAPPref can be added to the list to chose the top level access point. For the

KAfInet tier this type behaves in the same way as TConnSnapPref.

It is recommended that at most one TConnAPPref from each tier is added to the

TConnPrefList.

If no TConnAPPref is specified, then the default access point for the KAfInet

tier will be used for selection.

/** The connection preference requires that the connection waits until its selected access point is available

before starting. The start request does not complete until the connection is fully up.

Without this preference(e.g in the TConnPrefList), if the selected access point is unavailable due to contention or

lack of coverage, the RConnection::Start is errored immediately.

TConnAutoStartPref does not aid access point selection. When specified without any other preference in the

TConnPrefList, the default access point in the KAfInet tier will be selected.
