An association object is used to assign category attributes to the taxonomy and to
assign dynamic attributes to a specific control attribute. It is a list of control attribute
values and their assigned category/dynamic attributes. There is one [control-attribute-value
| category/dynamic-attribute] pair for each attribute assigned to a control attribute. In
the case of category attributes (which are controlled by the taxonomy) and dynamic
attributes that are controlled by a hierarchy attribute, the association object also
indicates if an attribute for a node can be inherited by its children nodes, meaning that
the attribute is assigned once to the parent node but also applies to all its children
nodes.
