multiple attribute instaces and radius variables (xlat)

FreeRAIUS documentation in 1.1.1 mentions a possibility of referencing specific AVPs in case of multiple instances of an attribute (%{Attr-Name[N]}). This is quite useful (and a nice addition!), but it doesn't seem to cover some situations (especially related to logging/accounting) where number of attribute instances is not known in advance. Is it possible to add something like %{Attr-Name[*]} that would expand to all values of an attribute and something like %{Attr-Name[#]} that would expand to number of attribute instances ? The toughest part of the above suggestion is which delimiter to use in case of [*] and if it is possible to make that delimiter configurable. -- Andriy Gapon
