Notes:

   * There are two Records here in the same Data Set.  Each record
     defines a different Selection Sequence.

   * If, for example, a different Selection Sequence is composed of
     three Selectors, then a different Options Template with three
     selectorId Information Elements (instead of two) must be used.

Section 6.4.1 says:

   Report MAY include only the final selector packetSelected, to act as

   of the Attained Selection Fraction.

Notes:

Should be plural: packet[s]Selected.

packetSelected is not defined and occurs nowhere else.
packetsSelected "contains the number of packets selected by a Selector in the Selection Sequence" which makes sense as the index into "that Selection Sequence".
