Composite Properties |
Composites are made up of fields. Each composite field has the following properties:
| Column | Purpose |
|---|---|
| Field name | Name of the field in the composite. |
| Data type | Either basic data type or other composite. Basic data types can be:
|
| Required | Is the field required (i.e. non-optional). When parsing a message, this property is only applicable when Strict Grammar Checking is checked in the Misc tab of the Options window. |
| Any Length | If checked, the field can be any length. |
| Max | The maximum length of the field, if Any Length is unchecked. |
Recursive references from composite to itself are not allowed. For example, a composite such as XAD cannot have the same composite (XAD) as one of its sub-composites.
