TRANS13 — report_heuristics

Summary: What is the exact semantics of the boolean argument report_heuristics of the
commit operation? Can heuristic exceptions be raised even if report_heuristics
is set to false? What is returned by commit, if report_heuristics is set to
false and the implementation knows that a heuristic situation has occurred
(e.g. in a situation where the transaction terminating process is also the
coordinator)?

-> When it is known that commit hasn"t completed properly, returning no
exception is not satisfactory in my opinion.

It would be good if the OTS spec could clarify this issue.
