built-in data type


The abstract declared-attribute type represents all element attributes, whether they are specified or only implied. If an attribute is implied, it will belong to the implied-attribute subtype of declared-attribute. Otherwise, if the attribute is specified or defaulted, its subtype will be specified-attribute.

Each declared-attribute instance has an associated attribute-declaration, which can be obtained through the declaration of operator.

Each item of the attributes shelf is a declared-attribute.
