This struct represent a meta attribute. Any declaration that has this attribute attached to itself is to be considered an attribute. That declaration should only be used as an attribute and never on its own.
Returns a tuple of all attributes attached to the given symbol. By default this will only include actual attributes (see orange.core.Attribute.isAttribute).
Evaluates to true if the given symbol is an attribute. An attribute is any declaration with the "orange.core.Attribute.attribute" attribute attached.
