DDS — DDS ISSUE# 17] Clarify consequence of changing partitions

Ref-17 PartitionQos_behavior_on_change

The specification does not make it clear whether changing the
PARTITION QoS on a Publisher or Subscriber affects the existing
DataReader or DataWriter establishing some "associations" that did not
exist before, or breaking associations that existed.

Furthermore the specification does not describe whether the
INCOMPATIBLE_QOS listeners/ status will be triggered

Given that partitions are intended to be used to separate logically
separate 'communication words' so that you can isolate things it would
seem that changing partitions should affect existing DataReader and
writers and not trigger the INCOMPATIBLE_QOS.

**PROPOSAL**

Modify section 2.1.3.9 to clarify that (1) changing the PARTITION QoS
on a Publisher or Subscriber does affect the existing DataReader or
DataWriter entities. It may establish new "associations" that did not
exist before, or break existing associations.

Also explain in section 2.1.3.9 that not matching the PARTITION QoS
does not trigger the INCOMPATIBLE_QOS listener nor change the
associated status.
