Semantics
The precise semantics of this attribute depend on the type of the enclosing data connector or data definition
Multi-Attribute definitions
Multi-input definitions refers to Attribute Definitions or Data Connectors which consume multiple attributes. The current supported definitions are:
- The Scripted DataConnector and AttributeDefinition.
- The templated Attribute Definition.
- The RDBMS and LDAP connectors.
In this case the attribute and all its values are made available to the enclosing definition. If an attribute of the same name has already been provided, then the values are combined.
Multi-Value Definitions
Multi-value definitions refers to Attribute Definitions or Data Connectors which consume attribute values. These values are often, but not always, from one definition. Nearly all attribute definitions are multi-value. The deprecated ComputedIdConnector is a degenerate Multi-Value Definition in that it requires a single value (which may come from multiple sources, all but one of which would be empty).
In this case all the attribute values are made available. Values from multiple attributes are combined.,
