For the attributes of complex composite types some subordinate attributes can be disabled for client-side access.
Disabled nested attributes are not passed to client in any way, unlike the unavailable attributes.
During content configuration, any subordinate attribute can be disabled. However, some attributes of some particular types will be passed to client if they are required for the subsequent restore of the application object.
As an example of using this property, let's look at a catalog object form. You can disable the tabular section of the attribute of CatalogObject type if it does not have to be displayed on the form.
The attribute disabling significantly decreases the overhead of data exchange between client and server.
