Hi Tony & WG, The changes which went into sections 4.3.2 & 4.4.13 do address my suggestions made earlier to the list. So I do support the current version.
With the option of having a configurable area prefix this delivers quite a powerful extension. Also the current text says: "Other uses of the Area SID are outside the scope of this document. " Maybe we could state instead: Other uses of the Area SID and area prefix are outside the scope of this document. Many thx, R.
