Distinguishable Data Objects of an Implicit Group
When a data object belongs to an implicit sequence, determining the component a
data object belongs to depends on the format of the sequence, the type definition
of a component, and the component properties.
Guidelines for Defining an Implicit Delimited Sequence
♦ If the type of a component has a terminator, that terminator must be different
from the delimiter of the explicit group. If the delimiter and terminator are
both defined as literal values, a type analysis confirms both have different
values.
♦ The type of a component cannot be a binary item whose length is not fixed or
sized.
