A unique name for each card in the map provides the ability to distinguish
between card objects.
For example, if two input cards are defined by the same type, these two input
cards may exist with the same type, but their card names are different. If the
name of the first card is Input1 and the second input card is Input2. If a
component Record exists as data objects in both these cards, the difference is
distinguishable Record in one input and Record in the other because the Record
types in the different cards have different names Record:Input1 and
Record:Input2.
Component Names in Map Rules
A component in a data object name is indicated by a colon :. The colon is the
separator between a data object and the group or category type it is a part of (or
the card name it is contained in).
For example, Record is a component of the data object OrderFile. The object
name for Record is Record:OrderFile.
