Message Sets: Local group logical properties
The logical properties of a local group include properties that specify the number of occurrences of the local group.
Valid children in a local group that depend on both Composition and Content Validation are shown in MRM content validation.
Property | Type | Meaning |
---|---|---|
Composition | Enumerated type | Define the order, and the number of occurrences, of the elements and groups in your messages. Composition does not affect the attributes in a complex type. Select from the following options:

Content Validation | Enumerated type | Content Validation is used only by the MRM domain.

See Message Sets: Combinations of Composition and Content Validation for further details of these options. |
Occurrences
Property | Type | Meaning |
---|---|---|
Min Occurs | Integer | Specify the minimum number of times that the object can repeat. The
default value is 1.
If the value is set to 0, the object is optional. With the exception of Max Occurs being set to -1, if a value is set for Min Occurs, it must be less than or equal to the value in Max Occurs. |
Max Occurs | Integer | Specify
the maximum number of times that the object can repeat. The default
value is 1. If this property is not set, the object cannot occur more than once. If this property is set to 0, it is interpreted as if the object does not exist in the message. It can also be set to -1, to indicate that the limit is unbounded and there is no maximum to the number of occurrences. |
