No mention is made in the ASN.1 of how to ensure
synchronous or asynchronous operation.
Similarly localised dependencies such as how many
outstanding requests may be supported, or timing
constraints are not specified.
A ROS exchange would typically consist of a connection
phase, a series of ROS invokations and responses and a
disconnection. Certain Applications might demand a
level of ;SPM_quot;Atomicity;SPM_quot; not provided within the
specification. This must be managed by higher-level
decisions of how ROS is used.
