CORBA3 — No portable way to turn IOR components into object-reference policies

For instance, OTS has a policy called OTSPolicy. This policy is
encoded in an IOR component with component id TAG_OTS_POLICY. This
policy governs how transactions are handled when invocations are made
on the object reference.

Problem:

As an end user I would like to be able to interrogate the value of this
policy. I would expect to be able to call CORBA::Object::_get_policy
with the OTS PolicyType identifier to retrieve the OTSPolicy and
subsequently determine the value. However, at present there is no
portable way to turn this IOR component into a policy.

This is in essence the same as issue 3615. Merge with 3615 and close this issue
