DDS4CCM11 — proposed simple spec extension for common DDS use case

In paragraph 7.2.2.1.2, a note about interface Reader says:

<< Note: This interface is the basis for a passive data reader (i.e. a component that just looks at the data as they are). It is also very useful for the reactive data getters (i.e. components that need to react to new data, whether they choose to get them in pull mode or be notified in push mode) in their initialization phase. This is the reason why all the DDS ports on the subscribing side will embed a Reader basic port.>>

This note may let people think that it is ONLY useful in initialisation phase, which is not true. A clarification sentence would avoid that misunderstanding.
