Using Fully Qualified Names when Referring to Objects
-----------------------------------------------------

When referring to another type, you can either use the target data type
without a namespace (in this case, the search will occur in the same
module you are working on), or you must specify the full namespace of
the target object. In particular, **partial namespace qualification is
not supported because it is naturally ambiguous**.

For example, suppose you have this type (using IDL syntax):

.. code-block:: IDL 

        module MyModule {
            module AnotherModule {
                struct BaseType {
                    short x;
                    short y;
                };
            }
        }

Then suppose you want to create another structure inside ``AnotherModule``
that extends ``BaseType``. You have two choices:

-   Use just the name ``BaseType`` to specify the base class
-   Use the fully qualified name ``MyModule::AnotherModule::BaseType``

*System Designer* does not accept partial qualification, such as
``AnotherModule::BaseType``, because it is ambiguous.
