                    <documentation>
                    Flag indicating whether each of the subdeployments within a .ear can access classes belonging to
                    another subdeployment within the same .ear. Setting this to false, allows the subdeployments to
                    see classes belonging to other subdeployments within the .ear.
                    For example:
                    myapp.ear
                     |
                     |--- web.war
                     |
                     |--- ejb1.jar
                     |
                     |--- ejb2.jar

                    If the ear-subdeployments-isolated is set to false, then the classes in web.war can access classes
                    belonging to ejb1.jar and ejb2.jar. Similarly, classes from ejb1.jar can access classes from ejb2.jar
                    (and vice-versa).

                    *Note that this flag, has no effect on the isolated classloader of the .war file(s). i.e. irrespective
                    of whether this flag is set to true or false, the .war within a .ear will have a isolated classloader
                    and other subdeployments within that .ear will not be able to access classes from that .war. This is
                    as per spec*
