DDS11 — Ref-232 Allow_reader_to_access_partition_of_writer

Some applications would like to see originating partition as part of
sample info. Thisis specially important if the application subscribes
with wildcards to any partition

There is a concern, however, with putting the information in the
SampleInfo as it is a cost that has to be paid every time a sample is
returned.

Perhaps the SampleInfo is just an interface so that there are
operations to access stuff and the cost can be performed as needed.

**PROPOSAL**

No concrete proposal as it would be hard to represent in IDL but it
would be nice if such API was offered.
