DDS — Ref-112 Value_of_data_for_DISPOSED_state

Section 2.1.2.5.3 of the specification does not clearly state that the
data_value and the sample_info sequences returned by the read* and
take* operations must be of the same length and are in one-to-one
correspondence

Furthermore, the specification does not describe what the element of
the DataSeq should be when the SampleInfo states that the
lifecycle_state is DISPOSED

Same issue when the lifecycle_state is NO_WRITERS

These should be clarified

**PROPOSAL**

This must be rephrased in accordance with the proposal in Ref-84.

State in section 2.1.2.5.3 that both sequences are of the same length
and in one-to-one correspondence

State that when the that when the liveness_lifecycle is DISPOSED
(NO_WRITERS or EXPLICIT) the last sample for the instance, that is the
one with instance_rank==0 has no corresponding data
