How to exclude files and paths for Swift-DocC compilation process?

Intro

I have a framework A and its dependency B. I wrote some documentation using DocC syntax for only framework A and would like to compile documentation for only this framework using Xcode and doing the following steps:

1. Choose a right scheme of framework A
2. Product → Build Documentation (⌃ ⇧ ⌘ D)

Expected

A generated documentation for only framework A.

In fact

It tries to compile a doc not only for framework A but for dependency B as well.

Problem

Unknown reason of failure. It happens because Xcode tries to create a doc for dependency B as well.

Questions

1. Is there any way to configure the process of building a doc excluding unnecessary files and paths?
2. If 1st question yes, so where and how?
3. Does a selected scheme affect on DocC compiler process at all? Or the compiler tries to handle all sources he has within .xcworkspace including all .xcodeproj and their dependencies inside workspace?

Details

FYI

All the best,

Ivan.

P.S. I'd been happy to see support Markdown's tables here with more rich visual experience.
