Create and possibly filter a sequence of items.
A StepExpr creates a sequence of items. It may consist of a
general step that includes primary expressions or of a step on some axis in
forward or reverse direction. This sequence can be filtered by using predicate
expressions that are defined in StepQualifiers. The value of the step
is determined by those sequence items that meet the predicate condition.
See AxisStep and GeneralStep for examples.
