RemarksSchemaElementDefinition are returned by {@link Service} objects and {@link Operation} objects to define the content of requests, replies and events. The {@link SchemaTypeDefinition} returned by {@link SchemaElementDefinition#typeDefinition()} may itself return SchemaElementDefinition objects when the schema contains complex items. SchemaElementDefinition objects are read-only and always created by the API, never by the application. The SchemaElementDefinition defines the symbolic name any constraints on this item and the SchemaTypeDefinition which represents instances of this item.
- An item which is optional in the schema has SchemaElementDefinition.MinValues == 0.
- An item which is mandatory in the schema has SchemaElementDefinition.MinValues >= 1.
- An item which is a single value has SchemaElementDefinition.MaxValues == 1.
- An item which is an array has SchemaElementDefinition.MaxValues > 1.
- An item which is an unbounded array has SchemaElementDefinition.MaxValues == SchemaElementDefinition.UNBOUNDED.
As well as the symbolic name, array constraints and other constraints this class also provides access to the description and status of the item.
