DDS12 — delete_contained_entities() on the Subscriber

Should delete_contained_entities() on the Subscriber (and even the DataReader or DomainParticipant) be allowed to return PRECONDITION_NOT_MET?

Summary:
As described in Section 2.1.2.5.2.6, delete_datareader() can return PRECONDITION_NOT_MET if there are any outstanding loans. In a similar fashion, should we allow delete_contained_entities() on the Subscriber (and even the DataReader or DomainParticipant for that matter) to also return PRECONDITION_NOT_MET in this situation?

Proposed Resolution:
Return PRECONDITION_NOT_MET when delete_contained_entities() is called on either the DataReader, Subscriber, or DomainParticipant when a DataReader has outstanding loans.

Proposed Revised Text:

Section 2.1.2.2.1.18 delete_contained_entities
Before the paragraph that starts with "Once delete_contained_entities returns successfully," add the paragraph
The operation will return PRECONDITION_NOT_MET if the any of the contained entities is in a state where it cannot be deleted.

Section 2.1.2.4.1.14 delete_contained_entities
Before the paragraph that starts with "Once delete_contained_entities returns successfully," add the paragraph
The operation will return PRECONDITION_NOT_MET if the any of the contained entities is not in a state where it can be deleted.

Section 2.1.2.5.2.14 delete_contained_entities
Before the paragraph that starts with "Once delete_contained_entities returns successfully," add the paragraph
The operation will return PRECONDITION_NOT_MET if the any of the contained entities is not in a state where it can be deleted. This will occur, for example, if a contained DataReader cannot be deleted because the application has called a read or take operation and has not called the corresponding return_loan operation to return the loaned samples.

Section 2.1.2.5.3.30 delete_contained_entities
Before the paragraph that starts with "Once delete_contained_entities returns successfully," add the paragraph
The operation will return PRECONDITION_NOT_MET if the any of the contained entities is not in a state where it can be deleted.
