+/**
+ * An implementation of the {@link AccessControl} interface that allows
+ * authorization using the permissions as specified in the given XML
+ * file.
+ * 
+ * The format of the XML file is specified in <a href="authz5_5.dtd"/>. It
+ * implements a role-based authorization at the operation level for each region.
+ * Each principal name may be associated with a set of roles. The name of the
+ * principal is obtained using the {@link Principal#getName()} method and no other
+ * information of the principal is utilized. Each role can be provided
+ * permissions to execute operations for each region.
+ * 
+ * The top-level element in the XML is "acl" tag that contains the "role" and
+ * "permission" tags. The "role" tag contains the list of users that have been
+ * given that role. The name of the role is specified in the "role" attribute
+ * and the users are contained in the "user" tags insided the "role" tag.
+ * 
+ * The "permissions" tag contains the list of operations allowed for a
+ * particular region. The role name is specified as the "role" attribute, the
+ * list of comma separated region names as the optional "regions" attribute and
+ * the operation names are contained in the "operation" tags inside the
+ * "permissions" tag. The allowed operation names are: GET, PUT, PUTALL,
+ * DESTROY, REGISTER_INTEREST, UNREGISTER_INTEREST, CONTAINS_KEY, KEY_SET,
+ * QUERY, EXECUTE_CQ, STOP_CQ, CLOSE_CQ, REGION_CLEAR, REGION_CREATE,
+ * REGION_DESTROY. These correspond to the operations in the
+ * {@link OperationCode} enumeration with the same name.
+ * 
+ * When no region name is specified then the operation is allowed for all
+ * regions in the cache. Any permissions specified for regions using the
+ * "regions" attribute override these permissions. This allows users to provide
+ * generic permissions without any region name, and override for specific
+ * regions specified using the "regions" attribute. A cache-level operation
+ * (e.g. {@link OperationCode#REGION_DESTROY}) specified for a particular region
+ * is ignored i.e. the cache-level operations are only applicable when no region
+ * name is specified. A {@link OperationCode#QUERY} operation is permitted when
+ * either the {@code QUERY} permission is provided at the cache-level for
+ * the user or when {@code QUERY} permission is provided for all the
+ * regions that are part of the query string.
+ * 
+ * Any roles specified in the "user" tag that do not have a specified permission
+ * set using the "permission" tags are ignored. When no {@link Principal} is
+ * associated with the current connection, then empty user name is used to
+ * search for the roles so an empty user name can be used to specify roles of
+ * unauthenticated clients (i.e. {@code Everyone}).
+ * 
+ * This sample implementation is useful only for pre-operation checks and should
+ * not be used for post-operation authorization since it does nothing useful for
+ * post-operation case.
