Issue 17363: When using GROUP access scope presentation QoS, allow for read/take outside of  begin_access and end_access block (data-distribution-rtf)
Source: Real-Time Innovations (Mr. Fernando Sanchez, )
Nature: Revision
Severity: Significant
Summary: Found by: Fernando Crespo
Severity: 


Problem: The DDS specification (section 7.1.2.5.2.8)
does not allow access to the DDS cache when the 
application wants to access data, but does not
care about the order across Data Writers. 


Proposed Resolution: 
When using GROUP access scope, allow both 
access patterns and do not return PRECONDITION_NOT_MET
error code when called read, take, etc. without first
called begin_access.  


Note: This also allows portability for applications which
do not care about the order across topics.
