Return type: declared-attribute
Returns: A declared-attribute that corresponds to the attribute-declaration.

Syntax

create-unspecified-attribute attribute-declaration

Purpose

The result of the create-unspecified-attribute operator depends on the attribute-default-declaration of the attribute-declaration:

If the default is attribute-declared-required, an error will be thrown.
If the argument declaration specifies a default or fixed value instead, the result will be a specified-attribute instance with the default value.
Otherwise, the result will be an implied-attribute instance.
