Dmitry, let me paste my answer i give to Jeff as an introduction to explain better the problem. First of all, I want to thank you to point me to different options. I will think about to refactoring everything i have or even build from scratch if I'm not able to build from what i already have.
For the requirements, It's not a problem to have a public constructor for the handle, in fact, i will need one for users. The real problem is to have constructors or function that i need to be visible from implementing packages and at the same time NOT visible from users that only are allowed to do a "with API.XXX"
I have the next requirements:
- I need to pack all calls from users in just one Package API Hierarchy.
- The details and complexity of the implementation needs to be outside of this API hierarchy as much as possible.
-I need to use tagged types as much as possible for the calls from users to API package. (I'm not a big fan of this also but its a requirement)
-This API tagged types needs to connect the API Side with the implementation packages.
-The user needs to set a limited number of callback procedure with this flavor: "Procedure (S : in out Tagged_APi_Type)"
-The Implementation package needs to trigger the procedure defined in the API. (Here comes to problems):
-->The implementation package needs to manipulate some hide part of the Tagged_API_Type when is triggered
------>Here comes the problem. From the implementing package is not possible to see the private part of the API package. I think because visibility is not related to type, is related to package where package exists.
