Use-cases

As a framework provider developer, I'd like to make some toolings based on the provider/datasource/resource schema definitions. The tool runs from with in the provider, and inspect different dimensions on the schemas.

Currently, the schemas have the following hierarchy:

terraform-plugin-framework/[resource|datasource|provider]/schema.Schema ------------------- impl --> | terraform-plugin-framework/internal/fwschema.Schema
                   |                                                                                 |
                   |                                                                                 |
              composed of                                                                         internal
                   |                                                                                 |
                   v                                                                                 |
 terraform-plugin-framework/[resource|datasource|provider]/schema.[Attribute|Block|...] --- impl --> | terraform-plugin-framework/internal/fwschema.[Attribute|Block|...]

It makes me have to duplicate the same code that processing the [resource|datasource|provider].[Schema|Attribute|Block] three times, as long as I want to define some intermidiate function/type that aims to hold any of these types. What I actually want is to use those internal interfaces types instead, so that I only need to maintain one code.

Attempted Solutions

Duplicates the logic to 3 copies.

Proposal

Exposing those interfaces in ./internal/fwschema package.
