Collections and sequence
Define order, repeated positions, matching and the scope of grouped actions.
Decide whether order is part of a stored value
Contrast an ordered sequence with an unordered selection.
Give repeated action names separate step identities
Keep a sequence occurrence distinct from its action label.
Specify whether a pattern must be consecutive
Distinguish adjacent matching from a merely ordered subsequence.
Keep display sorting separate from a stored manual order
Specify whether a sort changes presentation or the underlying sequence.
State whether a parent action changes its children
Define a grouped action’s depth instead of assuming a cascade.
