CAD11 — Model creation parameters

Where can one get the CadFeature::Parameter instances from to use in CadSystem::create_model() ?
As far as I know, the instance of a idl interface can only be created on the server (in a get method or in a factory) and I can see no way of creating empty CadFeature::Parameter instances.
Besides, why was CadFeature::ParameterSeq used on Model level (CadMain::Model::create_model(), CadMain::Model::get_parameter_set()) and not as in other places CosProperyService::Properties? It is not clear to me, what information is supposed to be behind these parameters.

This looks like a valid concern. We can fix this by using either CosProperyService::Properties in place of the CadFeature::ParameterSeq or we can created a CadFeature::ParameterFactory.

I suggest the use of Properties.
