The composition of the input and output cards shows the content of the type
definitions. Types on the cards are arranged in the order they appear in the data
stream. Types on the input and output cards are arranged in a compositional
hierarchy that shows the structure, layout, or composition of the data. This
composition hierarchy is different from the hierarchy in the type tree, which is a
classification hierarchy.
Each icon in the input and output card represents a data type. Icons that display a
plus sign (+) may be expanded. Icons that display a minus sign (-) may be
collapsed.
