Chapter 7 - Group Properties Explicit Format
Each line is the same length; Line has a fixed syntax. It is made up of Header,
which is fixed, followed by some items, all of which are fixed. Each is padded to a
fixed size or its minimum and maximum content size are equal. Ultimately, Line is
composed of items padded to a fixed size.
Guidelines for Defining a Fixed Group
♦ Each component must be a group with a fixed syntax or a fixed item. The item
is padded to a fixed size or its minimum and maximum content size are equal.
♦ Each component must have a specified range maximum. The maximum cannot
be
s.
♦ If a component range minimum is not equal to the maximum, content is not
required for optional component occurrences.
For example, if a component is the item ShippingAddress (0:1) and
ShippingAddress has a minimum content size of two characters, data may
either contain: 1) all pad characters, or 2) if content is in the data stream,
there must be a minimum of two characters for a ShippingAddress. If a
component is a group, no content is required for any of the items contained in
an optional occurrence of that component.
