### Namespace: http://midpoint.evolveum.com/xml/ns/public/common/common-3

Item Summary
Name | Type | Multiplicity | Description
--- | --- | --- | ---
key | property string | [0,1] | Localization key.
keyExpression | property ExpressionType | [0,1] | Localization key expression.
argument | property LocalizableMessageArgumentType | [0,-1] | Values for arguments.
argumentExpression | property ExpressionType | [0,-1] | Expressions to be evaluated to specific arguments, which are to be used as values for localized message parameters.
fallbackMessage | property string | [0,1] | Fallback message to be used when key couldn't be resolved.
fallbackMessageExpression | property ExpressionType | [0,1] | Fallback message expression to be evaluated to specific fallback message.

- ### Items

  - #### key

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Localization key. Mutually exclusive with keyExpression.

  - #### keyExpression

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Localization key expression. Mutually exclusive with the key.

  - #### argument

    Flags: RAM,runtime

    Multiplicity: [0,-1]

    Values for arguments. Mutually exclusive with argumentExpression: if at least one argument is used, no argumentExpression can be used, and vice versa.

  - #### argumentExpression

    Flags: RAM,runtime

    Multiplicity: [0,-1]

    Expressions to be evaluated to specific arguments, which are to be used as values for localized message parameters. Mutually exclusive with argument: if at least one argumentExpression is used, no argument can be used, and vice versa.

  - #### fallbackMessage

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Fallback message to be used when key couldn't be resolved. Mutually exclusive with fallbackMessageExpression.

  - #### fallbackMessageExpression

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Fallback message expression to be evaluated to specific fallback message. Mutually exclusive with fallbackMessage.
