When generating PSML output the "structure" context node is missing if a
display filter is used that causes the 1st packet in the capture not to be
displayed:

Example 1: (PSML with "structure" context node) display filter allows the first
packet to be displayed:

tshark -T psml -R 'frame.number >= 1 && frame.number <= 2' -r /tmp/capture.cap;
