=========================
Classification Attributes
=========================
Get the classification attributes of the classes in the DEXPI
Information Model.

Variables
=========

cls
    The class for which the attribute is declared.

attribute
    Name of the attribute.

rdl
    The RDL reference associated with the attribute in a
    DEXPI-compliant Proteus file.

classification_type
    The classification type of the attribute. See
    `Classification Types and Values <classification_types_and_values_overview.html>`_.

description
    Optional. A description of the attribute.

    .. note:: Descriptions may contain markup that is used to build the official PDF
       version of the DEXPI Specification. In the cached HTML, CSV, and Excel
       results below, this markup has been removed for better readability. For
       example, a description such as *The \\labeledref[class:]{ControlledActuator}
       of the <owner>* will be shown as *The ControlledActuator of the
       ActuatingSystem*.

is_proteus_generic_attribute
    A boolean indicating if the attribute is represented as a
    ``<GenericAttribute>`` in a DEXPI-compliant Proteus XML
    file.
